From Sahih Muslim (Hadith 6129):
Abu Huraira reported so many 'ahadith from Allah's Messenger (ﷺ) and one among them was that Allah's Messenger (ﷺ) is reported to have said:By Him in Whose Hand is the life of Muhammad, a day would come to you when you would not be able to see me, and the glimpse of my face would be dearer to one than one's own family, one's property and in fact everything. This hadith has been transmitted on the authority of Ishaq with a slight variation of wording
