When the Prophet ﷺ was taken on the night journey to the Aqsa Mosque, he began telling the people about it the next morning. Some who had believed in him and accepted his truthfulness turned away, and a group rushed to Abu Bakr and said, "Have you heard about your companion? He claims he was taken last night to Jerusalem."Abu Bakr asked, "Did he really say that?"They replied, "Yes."He said, "If he said it, then he has spoken the truth."They said, "You believe him when he claims he went to Jerusalem last night and returned before morning?"He answered, "Yes, I believe him in what is far greater than that. I believe him concerning news from the heavens that comes to him morning and evening."It was for this reason that Abu Bakr was called al-Siddiq, the Truthful.
لما أسري بالنبي ﷺ إلى المسجد الأقصى أصبح يتحدث الناس بذلك، فارتد ناس ممن آمنوا به، وصدقوه، وسعوا بذلك إلى أبي بكر، فقالوا: هل لك إلى صاحبك يزعم أنه أسرى به الليلة إلى بيت المقدس؟ قال: أو قال ذلك؟ قالوا: نعم. قال: لئن كان قال ذلك لقد صدق. قالوا: أو تصدقه أنه ذهب الليلة إلى بيت المقدس، وجاء قبل أن يصبح؟ قال: نعم إني لأصدقه فيما هو أبعد من ذلك، أصدقه بخبر السماء في غدوة أو روحة؛ فلذلك سمي أبو بكر الصديق.
Hakim narrated it (3/62), and from his route Bayhaqi in Dalail (2/360-361), from Muhammad bin Kathir Sanani, who said, "Muamar bin Rashid told us, from Zuhri, from Urwa, from Ayesha," and he mentioned it.Hakim said, "Its isnad is sahih." Its isnad is hasan, due to the discussion regarding Muhammad bin Kathir Sanani, and the conclusion is that his hadith is hasan when supported by corroborating narrations.
