(And whoever hopeth for the meeting with his Lord…) [18:110].
Said Ibn 'Abbas: “This verse was revealed about Jundub ibn Zuhayr al-'Amiri who said: 'I do the deed seeking Allah but I get happy when other people come to know about it'. The Messenger of Allah, Allah bless him and give him peace, said to him: 'Allah, exalted is He, is pure and does not accept except that which is pure. He does not accept that in which other than Him is associated'. Allah, exalted is He, then revealed this verse”.
Said Tawus: “A man said: 'O Prophet of Allah, I love striving in the way of Allah, but I also love to be seen!' Allah, exalted is He, revealed this verse [about this]”.
Mujahid said: “A man went to see the Prophet, Allah bless him and give him peace, and said: 'I give alms and keep my ties of kinship and do this only for Allah, glorious and exalted is He. However, when other people mention this and praise me for it, it makes me happy and I like it'. The Messenger of Allah, Allah bless him and give him peace, did not respond to him. Then, Allah, exalted is He, revealed (And whoever hopeth for the meeting with his Lord, let him do righteous work, and make none sharer of the worship due unto his Lord)”.
