Sahih al-Bukhari, Book 63, Hadith 134 (In-Book) ⓘ

Narrated Al-Bara: When the Prophet migrated to Medina, Suraqa bin Malik bin Ju'sham pursued him. The Prophet invoked evil on him, therefore the forelegs of his horse sank into the ground. Suraqa said (to the Prophet ), "Invoke Allah to rescue me, and I will not harm you. "The Prophet invoked Allah for him. Then Allah's Messenger felt thirsty and he passed by a shepherd. Abu Bakr said, "I took a bowl and milked a little milk in it and brought it to the Prophet and he drank till I was pleased."

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، قَالَ سَمِعْتُ الْبَرَاءَ ـ رضى الله عنه ـ قَالَ لَمَّا أَقْبَلَ النَّبِيُّ صلى الله عليه وسلم إِلَى الْمَدِينَةِ تَبِعَهُ سُرَاقَةُ بْنُ مَالِكِ بْنِ جُعْشُمٍ، فَدَعَا عَلَيْهِ النَّبِيُّ صلى الله عليه وسلم فَسَاخَتْ بِهِ فَرَسُهُ‏.‏ قَالَ ادْعُ اللَّهَ لِي وَلاَ أَضُرُّكَ‏.‏ فَدَعَا لَهُ‏.‏ قَالَ فَعَطِشَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَمَرَّ بِرَاعٍ، قَالَ أَبُو بَكْرٍ فَأَخَذْتُ قَدَحًا فَحَلَبْتُ فِيهِ كُثْبَةً مِنْ لَبَنٍ، فَأَتَيْتُهُ فَشَرِبَ حَتَّى رَضِيتُ‏.‏
