مَا أَسْنَدَ سَالِمٌ مَوْلَى أَبِي حُذَيْفَةَ
[Machine] He was with Abu Bakr on a rooftop during Ramadan while he was praying. Abu Bakr came to him and said, "Don't you eat, O Khalifa of the Messenger of Allah?" He gestured with his hand until he did that twice. When it was the third time, he said, "Bring me your food." So he ate, prayed two Rak'ahs, then entered the mosque and the prayer was established.
أَنَّهُ كَانَ مَعَ أَبِي بَكْرٍ ؓ عَلَى سَطْحٍ فِي رَمَضَانَ وَهُوَ يُصَلِّي فَأَتَاهُ فَقَالَ أَلَا تَطْعَمُ يَا خَلِيفَةَ رَسُولِ اللهِ؟ فَأَشَارَ بِيَدِهِ حَتَّى فَعَلَ ذَلِكَ مَرَّتَيْنِ فَلَمَّا كَانَ فِي الثَّالِثَةِ قَالَ «ائْتِنِي بِطَعَامِكَ» فَطَعِمَ وَصَلَّى رَكْعَتَيْنِ ثُمَّ دَخَلَ الْمَسْجِدَ وَأُقِيمَتِ الصَّلَاةُ
