The subject matter of this Surah indicates that it was revealed during the last stage of the Holy Prophet's residence at Makkah, when the Quraish were considering the question of killing or exiling or imprisoning him. At that time some of the unbelievers put this question (probably at the instigation of the Jews) to test him :'Why did the Israelites go to Egypt?'' This question was asked because they knew that their story was not known to the Arabs for there was no mention of it whatever in their traditions and the Holy Prophet had never even referred to it before.

This Surah takes its name from the word (ar-Ra'ad) (thunder) that occurs in v. 13. It is merely the symbolic name of the Surah and does not in any way mean that the Surah deals with the scientific problems connected with thunder.

The Surah takes its name from v. 35 in which mention has been made of Prophet Ibrahim (Abraham). But it does not mean that it contains the life story of Prophet Abraham. The name is merely a symbol lid the names of many other surahs, i.e., the Surah in which Abraham's mention has been made.

This Surah takes its name from v. 80.

This Surah is entitled Ar Rahman, the word with which it begins. This title, however, deeply relates to the subject matter of the Surah too, for in it, from the beginning to the end, the manifestations and fruits of Allah's attribute of mercy and grace have been mentioned.

The Surah takes its name from the word al-waqi`ah of the very first verse.

The Surah takes its title from the sentence, Wa anzalna' l-hadida, of verse 25.

This Surah is entitled Al Mujadalah as well as Al Mujadilah, the title being derived from the word tujadiluka of the very first verse. As at the outset mention has been made of the woman who pleaded with the Holy Prophet (upon whom be Allah's peace) the case of zihar pronounced by her husband and urged him to suggest a way out of the difficult situation in order to save her and, her children's life from ruin, and Allah has described her pleading by the word 'mujadalah', the Surah came to be known by this very title. If it is read as 'mujadalah', it would mean 'pleading and arguing', and if it is read as 'mujadilah', it would mean 'the woman who pleaded and argued.'

The Surah derives its name from the mention of the word al-hashr in verse thereby implying that it is the Surah in which the word al-hashr has occurred.

In verse 10 of this Surah it has been enjoined that the women who emigrate to dar al-Islam (the Islamic State) and claim to be Muslims, should be examined hence the title Al-Mumtahinah. The word is pronounced both as mumtahinah and as mumtahanah, the meaning according to the first pronunciation being 'the Surah which examines', and according to the second, 'the woman who is examined.'

The Surah derives its name from the sentence yuqatiluna fi sabil-i- hlsaff-an of verse 4; thereby implying that it is a Surah in which the word saff occurred.
