Ulum al Qur'an
Particular Persons
Often a general rule which became part of the Qur'anic revelation, was first revealed in response to the circumstances or needs of a particular person, e.g. Sura 2:196:
'... And if any of you is ill, or has an ailment in his scalp (necessitating shaving) he should in compensation either fast or feed the poor or offer sacrifice ...' Ka'b bin 'Ujra said this verse - and if one of you is ill or has an ailment in his scalp, - was revealed concerning me. I had lice on my head and I mentioned this to the Prophet and he said: Shave (your head) and compensate by fasting three days or a sacrifice or feed six poor, for each poor one Sa'. [Muslim, II, Nos. 2735, 2738, 2739; Wahidi, op.cit., p.31. One sa' is a cubic measure of approx. 2.6 kg.]
This is again an example of the Prophet himself explaining the revelation in detail. At other times such revelation could not be applied but to the respective person. The best example of such a revelation is Sura Lahab (111) already referred to above. Other examples are references to the Prophet Muhammad in the Qur’an, such as e.g. Sura 75: 16:
[Bukhari. VI. No. 451.]Narrated Ibn 'Abbas (as regards Allah's statement) 'Move not your tongue concerning (the Qur'an) to make haste therewith' (75:16).
When the Angel Gabriel revealed the divine inspiration to Allah's Apostle he moved his tongue and lips, and that stage used to be very hard for him, and that movement indicated that revelation was taking place. So Allah revealed in Sura al-qiyama which begins: 'I do swear by the Day of Resurrection ...'
The Verses: 'Move not your tongue concerning (the Qur'an) to make haste therewith. It is for us to collect it (Qur'an) in your mind and give you the ability to recite it by heart' (75:16-17).
