Ulum al Qur'an
Several Asbab and One Revelation
From the reports of the sahaba it appears that particular passages of the Qur'an were revealed in response to more than one event, situation or question, or that the application of a particular passage of the Qur'an was for more than one particular occasion, as pointed out above.
Examples:
Sura al-ikhlas (112) firstly responds to the mushrikun in Makka before the hijra, and secondly to the ahl al-kitab encountered in Madina after the hijra. [Itqan, I, p.35; Wahidi, op.cit., pp.262-3.]
Another example is Sura 9: 113:
This aya was revealed firstly in connection with the death of the Prophet's uncle Abu Talib, where Muhammad said 'I will keep on asking (Allah for) forgiveness for you unless I am forbidden to do so'. Then there was revealed: it is not fitting for the Prophet and those who believe that they should pray for forgiveness for pagans, even though they be of kin, after it has become clear to them that they are the companions of the Fire. [Bukhari, VI, No. 197.]
The other occasion reported is when the Companions and in particular 'Umar b. al-Khattab found the Prophet shedding tears when he visited the graveyard. The Prophet explained that he had visited his mother's grave and that he had asked his Lord's permission to visit it which had been granted to him and that he had also asked his Lord's permission to pray for her forgiveness which had not been granted to him and the above aya had been revealed. [Wahidi, op. cit., p. 152.]
