I asked Ja'far ibn Muhammad (as), "How many times did the Messenger of Allah (swt) (peace and blessings be upon him and his family) perform Hajj?" Imam (as) replied: "Twenty Hajj pilgrimages secretly, and in each pilgrimage, During each pilgrimage, he would pass by the Ma’zamain, where he would stop and relieved himself." I asked him: "O son of the Messenger of Allah (swt), why would he dismount there to relieve himself?" Imam (as) replied: "Because it was a place where idols were worshipped, and from there was taken the stone used to carve Hubal, the idol that Imam Ali (as) threw from the top of the Kaaba after climbing on the back of the Messenger of Allah (swt) (peace and blessings be upon him and his family). The Prophet ordered that it be buried near the gate of Banu Shaybah, which is why entering the mosque from the Gate of Banu Shaybah became a Sunnah." Sulayman then asked: "Why does the proclamation of 'Allahu Akbar' alleviate the burden at that place?" Imam (as) replied: "Because the servant's saying, 'Allah (swt) is greater,' means 'Allah (swt) is greater than being like the carved idols or the gods worshipped instead of Him.' Indeed, Iblis and his devils narrow the passage for the pilgrims in that spot. When they hear the takbir (proclamation of Allah’s (swt) greatness), they flee with their devils, and the angels chase them until they fall into the green abyss." I asked: "Why is it recommended for a first-time pilgrim (Saroorah) to enter the Kaaba while it is not required for someone who has performed Hajj before?" Imam (as) replied: "Because the first-time pilgrim is fulfilling an obligation and has been invited to Allah’s (swt) House; thus, it is proper for him to enter the House to which he has been invited, so that he may be honored within it." I asked: "Why is shaving the head obligatory for a first-time pilgrim but not for one who has performed Hajj before?" Imam (as) replied: "To mark him with the symbol of the secure ones. Do you not hear the words of Allah (swt), the Mighty and Majestic: You will surely enter the Sacred Mosque, if Allah wills, in security, with your heads shaved and [hair] shortened, not fearing [anyone]'?" I asked: "Why is the standing at Al-Mash'ar Al-Haram an obligation?" Imam (as) replied: "So that by doing so, one may earn the right to tread in the central courtyard of Paradise."
