Hadith 1185

Narrated Jabir (bin 'Abdullah) (RA): A man said on the day of the Fath, "O Messenger of Allah, I have vowed that if Allah opens the conquest of Makkah at your hands I shall pray in Jerusalem." He replied, "Pray here." He asked him again and he replied, "Pray here." He asked him again and he replied, "It's up to you, then." [Reported by Ahmad and Abu Dawud. al-Hakim graded it Sahih (authentic)].
