When the Prophet ﷺ migrated to Medina, Suraqa bin Malik bin Ju'sham pursued him. The Prophet ﷺ 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 ﷺ invoked Allah for him. Then Messenger of Allah ﷺ 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 ﷺ and he drank till I was pleased."  

لَمَّا أَقْبَلَ النَّبِيُّ ﷺ إِلَى الْمَدِينَةِ تَبِعَهُ سُرَاقَةُ بْنُ مَالِكِ بْنِ جُعْشُمٍ فَدَعَا عَلَيْهِ النَّبِيُّ ﷺ فَسَاخَتْ بِهِ فَرَسُهُ قَالَ ادْعُ اللَّهَ لِي وَلاَ أَضُرُّكَ فَدَعَا لَهُ قَالَ فَعَطِشَ رَسُولُ اللَّهِ ﷺ فَمَرَّ بِرَاعٍ قَالَ أَبُو بَكْرٍ فَأَخَذْتُ قَدَحًا فَحَلَبْتُ فِيهِ كُثْبَةً مِنْ لَبَنٍ فَأَتَيْتُهُ فَشَرِبَ حَتَّى رَضِيتُ  

When the Messenger of Allah ﷺ came from Makkah to Madinah, the Messenger of Allah ﷺ got thirsty. They passed by a herd of sheep, Abu Bakr as Siddeeq said: I took a cup and milked a cupful of milk for the Messenger of Allah ﷺ. I brought it to him and he drank until I was pleased,  

سَمِعْتُ الْبَرَاءَ قَالَلَمَّا أَقْبَلَ رَسُولُ اللهِ ﷺ مِنْ مَكَّةَ إِلَى الْمَدِينَةِ عَطِشَ رَسُولُ اللهِ ﷺ فَمَرُّوا بِرَاعِي غَنَمٍ قَالَ أَبُو بَكْرٍ الصِّدِّيقُ فَأَخَذْتُ قَدَحًا فَحَلَبْتُ فِيهِ لِرَسُولِ اللهِ ﷺ كُثْبَةً مِنْ لَبَنٍ فَأَتَيْتُهُ بِهِ فَشَرِبَ حَتَّى رَضِيتُ  

When Messenger of Allah ﷺ went forth from Mecca to Medina, Suraqa b. Malik b. Ju'shum pursued him. Messenger of Allah ﷺ invoked curse upon him, and his horse sank (in the desert). He (Suraqa) said: (Messenger of Allah), invoke blessings for me and I will do no harm to you. He (the Holy Prophet) then supplicated Allah. (At that time) he (the Holy Prophet) felt thirsty, and they happened to pass by a shepherd. Abu Bakr Siddiq said: I took hold of a bowl and milked some milk into it for Messenger of Allah ﷺ and gave it to him. He drank it and I was pleased. (Using translation from Muslim 2009b)  

سَمِعْتُ الْبَرَاءَ بْنَ عَازِبٍ يَقُولُ لَمَّا أَقْبَلَ رَسُولُ اللهِ ﷺ مِنْ مَكَّةَ إِلَى الْمَدِينَةِ قَالَ فَتَبِعَهُ سُرَاقَةُ بْنُ مَالِكِ بْنِ جُعْشُمٍ فَدَعَا عَلَيْهِ رَسُولُ اللهِ ﷺ فَسَاخَتْ بِهِ فَرَسُهُ فَقَالَ ادْعُ اللهَ لِي وَلَا أَضُرُّكَ قَالَ فَدَعَا اللهَ لَهُ قَالَ فَعَطِشَ رَسُولُ اللهِ ﷺ فَمَرُّوا بِرَاعِي غَنَمٍ فَقَالَ أَبُو بَكْرٍ الصِّدِّيقُ فَأَخَذْتُ قَدَحًا فَحَلَبْتُ فِيهِ لِرَسُولِ اللهِ ﷺ كُثْبَةً مِنْ لَبَنٍ فَأَتَيْتُهُ بِهِ فَشَرِبَ حَتَّى رَضِيتُ
