KNOW THAT THIS is mustaḥabb, so much so that it is mustaḥabb for a man with his wife and other dependants who he suspects have lifted their hands while they still need to eat, even only a little. Here is some of the evidence for this.
We relate from the Ṣaḥīḥ of al-Bukhārī that Abū Hurayrah
narrated a long hadith which includes manifest miracles of the Messenger of Allah
. Once when Abū Hurayrah
was extremely hungry he sat in the street requesting those who passed by him to recite the Qur’ān to him, hoping that they would invite him [to a meal]. Then the Messenger of Allah
sent him to the People of the Ṣuffah and he made them all drink their fill from a single goblet [of milk]. He recounted the hadith until he said: “The Messenger of Allah
told me: ‘Only I and you remain.’ I said: ‘You have spoken the truth, Messenger of Allah.’ He said: ‘Sit and drink.’ So I sat and drank. He said: ‘Drink.’ And I drank. He continued to say: ‘Drink’ until I said: ‘No, by Him Who has sent you with the truth, I cannot find any room for it.’ He said: ‘Let me see it.’ I gave him the goblet, and he praised Allah and mentioned His name and drank the remaining milk.” [1].
