A'isha reported that Allah's Messenger (ﷺ) in his (last) illness asked me to call Abu Bakr, her father, and her brother too, so that he might write a document, for he feared that someone else might be desirous (of succeeding him) and that some claimant may say:
I have better claim to it, whereas Allah and the Faithful do not substantiate the claim of anyone but that of Abu Bakr.
