When Omar visited the home of Prophet Muhammad

 I visited Allah's Messenger (ﷺ), and he was lying on a mat. I sat down and he drew up his lower garment over him and he had nothing (else) over him, and that the mat had left its marks on his sides. I looked with my eyes in the store room of Allah's Messenger (ﷺ). I found only a handful of barley equal to one sa' and an equal quantity of the leaves of Mimosa Flava placed in the nook of the cell, and a semi-tanned leather bag hanging (in one side), and I was moved to tears (on seeing this extremely austere living of the Holy Prophet), and he said: Ibn Khattab, what wakes you weep? I said: Apostle of Allah, why should I not shed tears? This mat has left its marks on your sides and I do not see in your store room (except these few things) that I have seen; Ceasar and Closroes are leading their lives in plenty whereas you are Allah's Messenger. His chosen one, and that is your store! He said: Ibn Khattab, aren't you satisfied that for us (there should be the prosperity) of the Hereafter, and for them (there should be the prosperity of) this world?
