Tarabi rakata number is proven by Shari'a's authentic document. Acceptable sources have been reported that Hazrat Rasulullah (PB) had read twenty rakat tarabi with the companions. The work of the Companions was similar to that. Some of the people of Hazrat Rasulullah (pbuh) have proved to be untrustworthy in the judgment of the twenty rak'ah Tarabi, but the work of the Companions of the Companions in the pure sources proves that the Sahabaye karam from Harijat Rasulullah (peace be upon him) has been taught twenty rak'at. In the continuous activities of Amirul Mu'minin Hazrat Umar Farooq (ra) - so far, twenty rakat tarabi of Makkah Sharif's Masjidul Haraam and Medina Sharif's mosque, including all the mosques, are read in the mosque. Eight Rakat Tarabi was not in circulation at this time.
In 1284, the Ahl al-Hadith scholars of India made a division between the eight rakats and divided them into the consummate maskala of the Ummah. Then the other Ahl al-Hadiths opposed it. Then some scholars of Arabia also agreed with him. But most of the scholars of the Arab world are twenty rakat tarabi.
During the time of Hazrat Umar (ra) - the work of the disciples
One. Yazid bin Khusifa (RA) said, Sahabi Saib bin Yazid (ra) said, during the time of the companions Hazrat Umar ibn al-Khattab (ra) - twenty rakat tarabi used to teach Ramadan in the month of Ramadan. He also said that they used to recite hundreds of verses in Salat and in the time of Hazrat Uthman bin Affan (ra) - due to long prayers, some of them (some) would stand on the rocks. -As Sunanul Kubra and Baihaqi, 2/496/488
In other sources, Sahabi Sa'ib bin Yazid said, "We used to have twenty rakats and witr during the time of Hazrat Umar ibn al-Khattab (ra)." -As Sunanul Kubra, Baihaqi-1 / 266-268
Two Tabei Ibn Abi Jubayb (R) said, during the time of Hazrat Umar (ra) - Ramadan Qiyama, Tarabi was 23 rakats. -Abdur Razzak in Musnaf, Hadith: 7733
The source of the hadith is pure. In it, the purpose of 23 rakats is that, 20 Rakat Tarabi and three Rakat Vitr.
Three Tabe'i Abdul Aziz bin Rufai (R) said, Ubai bin Kaab (Ram) used to distribute twenty rakat tarabi and three rak'ah witr with the people of Madinah in Ramadan. - Ibn Abi Shaibah in Musnafa: 2/285/7766
Four. Tabei Yahya bin Saeed Ansari (RA) said, "Umar ordered a person to read twenty rakats with the people." - Ibn Abi Shaibah in Musnafa: 2/285/7764
Five Tabei Yazid bin Ruman (RA) said, during the time of Hazrat Umar Ibn al-Khattab (ra) - people used to read twenty-three rakats in Ramadan. -Muatta Malik, Hadith: 380
During the time of Hazrat Ali (ra) - the work of the disciples
The famous Tabe'i Imam Abu Abdur Rahman Sulami (R) said, Ali (H) called for the Hafez in Ramadan and one of them ordered people to read twenty rakats with the people. He said, Ali (r.) Used to distribute them with witr. -Sunanul Baihaqi: 2 / 496-497 / 4291
Tabe'i Abul Hasna (R) said, Ali (R) ordered a person, that he should read twenty rakat tarabi with the people. - Musnaf Ibn Abi Shaiba: 2/285/7763
Based on the combined descriptions of the above descriptions and on the basis of the unanimous action of the Sahabi-Tabein, and on the combined continuous action of the era, the scholars have suggested that twenty rakat tarabi Sunnay Moayakkada It would be a sin to leave the Sunkat Moakkad if you read it without any hesitation.
Those who are now promoting eight Rakat Tarabi, their most powerful document is a hadith of Bukhari Sharif, which is not about Tarabi, but the hadith is a hadith related to Tahajjud. It has been narrated that Hazrat Rasulullah (pbuh) used to perform eight rakats by performing four rak'ats outside Ramadan and Ramadan. However, we know that there is no Tarabi outside Ramadan and Tarabi prayers are two rakatas. If eight rak'ats were proved from the Prophet (peace be upon him), then the Companions would not have used twenty rakats against the Messenger of Allah (PBUH). NUJUBILLA!
Tarabi massyala
Masala: Twenty Rakat Tarabi prayers Balega Malegaon and Sunkaya Moakakada on all Tarabi is not necessary on a sick and sick person, but if there is no pain, read them too. -adadul Muhtar: 1/742
Masala: Tarabir prayers are offered in congregation, Mustahab, but earning will be realized even after earning. -Babyway Sanaay: 1/290
Masala: If some rakat is run from the congregation of Tarabi, then read it after the weekly prayers. -Radadul Muhtar: 2/44
Masalaah: It is not legal for anyone to be named after Above to Nabell Hafez. -Majmaul Anhur: 1/167, Hedayah: 1/38, Al-Bahrur Raik: 1/359
At Khaatan several masters of the Qur'an
Mashawala: Bismillah at the beginning of every surah, which is the circumcision, without any obligatory prayer, Nufal or Tarabi. But Bismillah silently read the circumcision Therefore, during the recitation of Tarabi, in the beginning of every Surah during the Qur'an, the uncertainty of the Sun But since Bismillahir Rahmanir Rahim is also a verse of the Qur'an; Therefore, the completion of any of the blessings of the devotees will be fulfilled if Bismillah falls in the beginning of any Surah. At the beginning of every Surma, there is no problem even if Bismillah is read in its own words. There is a time to act on both of them. -Dadadul Muhtar: 1/490
Masala: In the eyes of Islamic Shari'ah, should not be hasty enough to offer prayers in the mosque, and should not wait for Imam Sahib to finish Salat after waiting for another. The correct method of giving a luma is to give Imam Sahib a chance to repeat the verse; Even if Imam does not take the correctness, then there will be no harm if the Mukta Lama is offered. If Hafiz does not wait for the person to wait in the Qur'an, if he does not wait for the nomination of Tarabi, then there will be no difficulty if you do not give him a fame. However, after the recurring verses, after the recitation of Surat Fatehah. -Raddul Muhtar: 1/623
Taraabi did mistake in prayer
When standing in the second rak'at of Tarabi prayer, standing before the sajdah in the third rak'ah, if you remember and recited Tashahhud and sajdaye Sahu, then the recitation and prayers will be purified. If you prostrate in the third rak'ah, then the fourth rak'ah will be mixed. In this, the last two rak'ahs will be declared as the Salat of Tara and due to not having the last meeting, the first two rak'ahs will not be considered as Tarabi, due to recitation and recitation. -Babayeus Sanaaye: 1/889, Raddul Muhtar: 2/35, Fatwai Hindia: 1/118
If a person starts the routine prayers of four rak'ahs, and after meeting two rak'ahs, after meeting four rak'ats without meeting, then if he performs Salat after the prayer, only the last two rak'ahs will be considered as Tarabi. -Al Bahrur Rayike: 2/117
Sit Tarabi prayers
Tarabi prayers are valid through ruku-sajdar on the ground. Similarly, when performing Ruku Sajdah prayers regularly on the chair during the time of Tarabir, it is also valid. But if you do so without any excuse you will not get full reward for the prayer, but you will get half reward. But yes, if the person capable of prostrating ruku is sitting in the chair and praying through the ruku sajdar, the prayer will not be purified. -Fatawaiya Hinadi: 1/118
Tarabi salat is very important for us.
