So they would not – if they were in Al-Madeenah, visit his grave, and nor would they come to it – not for du’aa or for other than it. Rather they would come to his Masjid, and for every prayer they would be in his Masjid, and other than his Masjid, and they would say: ‘As-salaamu ‘alaika ayyuhan Nabi wa rahmatullaahi wa barakaatuhu’ and they would send salaat upon him and would ask for him to be given the waseelah when they would hear the adhaan – just as he had taught them in his Sunnah. The welfare in this is mighty, since what is achieved by way of this is multiplied in comparison to visiting his grave, whilst they also feared that it could be a pretext/excuse towards shirk, and constant visitation, and idolatry.
So this fear arose when it was possible to enter upon him, so when they blocked that – they prevented the people from entering upon him. Thus there was no way anyone could to make the well known visit, and no shirk, and not taking his grave as idol worship, and thus no one could but then pray except to his Masjid, and his Masjid is not his grave nor his home, rather his Masjid was built for the five daily prayers – and other than them.
