“Yes, I believe him with regard to something even more than that…
According to Al-Bayhaqi, Ibn Shihab said: Abu Salamah bin `Abdur-Rahman said:
Some people from Quraish went to Abu Bakr and said, “Have you heard what your companion is saying He is claiming that he went to Bayt Al-Maqdis and came back to Makkah in one night!” Abu Bakr said, “Did he say that” They said, “Yes.” Abu Bakr said, “Then I bear witness that if he said that, he is speaking the truth.” They said, “You believe that he went to Ash-Sham [Greater Syria] in one night and came back to Makkah before morning” He said, “Yes, I believe him with regard to something even more than that. I believe him with regard to the revelation that comes to him from heaven.” Abu Salamah said, from then on Abu Bakr was known as As-Siddiq (the true believer).
