How sound is the statement that Al-Aqsa Mosque was built forty years after Al-Masjid Al-Haram, and who built it?

The statement that Al-Aqsa Mosque was built 40 years after Al-Masjid Al-Haram is sound, based on what was authentically reported from Abu Dharr (may Allah be pleased with him) in the two Sahih collections. Scholars have differed regarding who built it the first time. Some say it was Adam (peace be upon him), while others say it was Abraham (peace be upon him). The most preponderant opinion is that it was Jacob (peace be upon him). As for the construction by Solomon (peace be upon him), it was a renovation, not an initial founding, given the long period exceeding 40 years between him and Abraham (peace be upon him).
