(20) باب جَوَازِ اسْتِتْبَاعِهِ غَيْرَهُ إِلَى دَارِ مَنْ يَثِقُ بِرِضَاهُ بِذَلِكَ وَيَتَحَقَّقُهُ تَحَقُّقًا تَامًّا وَاسْتِحْبَابِ الاِجْتِمَاعِ عَلَى الطَّعَامِ
Anas b. Malik reported this incident pertaining to the feast given by Abu Talha to Allah's Apostle (ﷺ) with the addition of these words:
" Abu Talha stood at the door (to welcome the honourable guest) until Allah's Messenger (may peacec be upon him) came there, He (Abu Talha) said to him: Allah's Messenger, the thing (we intend to offer you as a meal) is small in quantity. Thereupon he (the Holy Prophet) said: Bring that, for Allah will soon bless it (and increase it).
