Salim bin Abdullah bin Umar bin al Khattab may Allah be pleased with him on asking all the needs from Allah.
Hisham bin Abdul-Malik entered the Kaaba, and saw Salim bin Abdullah bin Umar bin Al-Khattab may Allah be pleased with him, and he said: O Salim! Ask me whatever you need. Salim replied: I am ashamed of Allah to ask another person in His house (Masjid al haram). When they left (came outside the Masjid), he (Hisham) again said: Now ask me something (as we are not in the house of Allah now). Salim said to him: From the needs of this world, or from the needs of the Hereafter? Hisham said: From the needs of the world (as he was not able to give anything from hereafter). Salim said: By Allah, I did not ask the world from the one who owns it(Allah), so how can I ask it from the one (meaning Hisham) who does not own it?
