وَعَنْ بُرَيْدَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: دَخَلَ بِلَالٌ عَلَى رَسُولِ اللَّهِ ﷺ وَهُوَ يَتَغَدَّى، فَقَالَ رَسُولُ اللَّهِ ﷺ: «الْغَدَاءَ يَا بِلَالُ». قَالَ: إِنِّي صَائِمٌ يَا رَسُولَ اللَّهِ! فَقَالَ رَسُولُ اللَّهِ ﷺ: «نَأْكُلُ رِزْقَنَا، وَفَضْلُ رِزْقِ بِلَالٍ فِي الْجَنَّةِ». «أَشَعَرْتَ يَا بِلَالُ! إِنَّ الصَّائِمَ تُسَبِّحُ عِظَامُهُ، وَيَسْتَغْفِرُ لَهُ الْمَلَائِكَةُ مَا أُكِلَ عِنْدَهُ».
Translation: Buraydah relates that Bilal entered while the Messenger of Allah ﷺ was eating his midday meal. The Prophet ﷺ invited Bilal to eat. Bilal explained respectfully that he was fasting. The Prophet ﷺ described Bilal’s remaining share of provision as being in Paradise and spoke of the merit of a fasting person: his bones glorify Allah, and angels seek forgiveness for him while food is being eaten in his presence.
Two good manners appear together: the host offered hospitality and the guest courteously explained his situation. The Prophet ﷺ also honored the value of fasting.
يَتَغَدَّى means “was eating the midday meal,” while إِنِّي صَائِمٌ means “I am fasting.” Source: al-Bayhaqi, Shuʿab al-Iman
