Surah An-Nisa (Arabic: سورة النساء ) , Sūratu an-Nisā, " meaning woman") is the fourth surah of the Muslim religious book Quran , with 16 verses and 24 ruku's. Surah An-Nisa has been revealed in Medina. This surah talks about how Muslims should lead their lives and how they should be united. This Surah is the sum of several speeches. Probably from the end of the third Hijri to the end of the fourth Hijri or from the beginning of the fifth Hijri, different parts of it were revealed at different times. Although it is not possible to say exactly from which verse to which verse a revelation was included in the discourse and what was the time of its revelation , some provisions and events have been pointed out somewhere which help us to know the date of their revelation from tradition. . So with the help of these we can point out a general limit of these speeches containing these provisions and hints. As we know, the provisions regarding the distribution of inheritance and the rights of orphans were revealed after the battle of Uhud. Then seventy Muslims were martyred. As a result of this incident , the question arose as to how the inheritance of the martyrs would be distributed in different houses of the small settlements of Medina and how the interests of the orphans they left behind would be protected . On the basis of this , we can assume that the first four ruku 's , and the first three verses of the fifth ruku 'will be revealed at this time. We find in the hadith the tradition of performing the prayer of fear (praying while fighting) in the battle of Jatur Rika. This battle took place in the 4th Hijri. Therefore , it can be inferred here that the speech (15 Ruku) in which the rules of prayer have been explained will have been revealed in the near future. Bani Nadir was expelled from Medina in the month of Rabiul Awal of the 4th Hijri. So the last warning that was given to the Jews in this speech was , "Believe me, before I turn your backs on you." Tayammum was allowed due to lack of water during the battle of Banil Mustaliq. And this battle took place in the fifth Hijri. Therefore, it should be remembered that the speech in which (7th Ruku) mentioned Tayammum was revealed at that time.
