then he said...
then he said: I said no, he said (PUH) then: it was one of the greatest Angels that God, the Exalted, did Have and when God took the covenant from the Angels, he was the first to admit it and so God made him the guardian for all of His creation and Gave him the covenant to keep and Decided to Make all the creations to renew their covenants with him each year, then God made him in company with Adam in paradise to remind him of the covenant and renew it each year, so when Adam did the sin and got out of paradise, God made him forget the covenant that He took over him and his descendants, for Muhammad and his viceroy and his descendants the protected against wrong doings, and Made him buffled and lost, but when He relented toward Adam He made this Angel in the picture of a white pearl and Sent it down from paradise to Adam when he was in the lands of India.
When Adam saw this, he got pleased though he didn't know what it was except it is some treasure, then God made him speak and said: O Adam, did you know me? then Adam said: no! then he answered: O yes, the demon overcame you and made you forget to praise your Lord, then he changed to his true shape as it was in paradise with Adam (PUH) and said to Adam: where is the covenant?
And when Adam remembered that jumped to him and cried and kissed him and renewed his covenant, then God changed him to a clear white pearl and Adam (PUH) carried him over his shoulders for his honour, and when he gets tired, Gabriel (PUH) would take it over, until they got to Mecca.
It was there in Mecca that Adam kept it and renew his covenant every day and night and when God wanted to build the Kaba and sent Gabriel for this purpose and started in building, made this stone and it is the white pearl in the corner that it is in nowadays, and he (Gabriel) sactified God and praised Him, and that's why the law goes for praising and sanctifying everytime being in front of the corner that carries the Holy stone, and so it is until this very day.
One of the religious duties to do when visiting the Holy House is to come to the Black Stone and kiss it if it was possible, or raise up the hand towards it and say: O Lord my fidelity I've done, and my covenant I've made to Testify me with the deed.
