Sahih Muslim: Book 36, Hadith 232

Aflah, the freed slave of Abu Ayyub Ansiri, reported: Allah’s Messnger (ﷺ) had alighted in his house (viz. of Abu Ayyub Ansari at the time of his emigration to Medina) and he occupied the lower storey, whereas Abu Ayyub Ansari lived in the upper storey. One night, Abu Ayyub Ansari got up and said (to himself): (How unfortunate it is) that we walk above the head of Allah’s Messenger (ﷺ), so they went aside and spent the night in a nook and then told Allah’s Apostle (ﷺ) about it whereupon Allah’s Apostle (ﷺ) said: The lower storey is more comfortable (for me). but he (Abu Ayyub Ansari) said: We (would not live) over the roof under which you live. So Allah’s Messenger (ﷺ) shifted to the upper storey, whereas Abu Ayyub Ansari shifted to the lower storey; and he (Abu Ayyub Ansari) used to prepare food for Allah’s Apostle (ﷺ) ; and when it was brought (back) to him he asked (to locate) the part, where his fingers had touched (the food), and he followed his fingers on that part where his fingers (those of the Holy Prophet) had touched it. (One day) he prepared food which contained garlic, and when it was returned to him he asked (to locate) the part which the fingers of Allah’s Apostle (ﷺ) had touched. It was said to him that he had not eaten (the food). He (Abd Ayyub Ansari) was distressed and went up to him (to the Holy Prophet) and said: Is it forbidden? But Allah’s Messenger (ﷺ) said: No, (it is not forbidden), but I do not like it. and he (Abu Ayyub Ansari) said: I also do not like what you do not like or which you did not like. He (Abu Ayyub Ansari) said: (The Prophet did not eat garlic) as Allah’s Apostle (ﷺ) was visited (by angels) and brought him the message of Allah.
