Abrahamic prayer & advent of Prophet Muhammad (pbuh)

Advent of Prophet Muhammad (pbuh) on 12th Rabbi-ul-Awal in the year 570 A.D had been prayed for by Syedena Ibrahim (A.S) and his son Syedena Ismail (A.S) after they founded Biet’u’llah: Kabbah, praying to  Allah (SwT) to accept their services and make them and their progenies Muslims:  

‘And remember Abraham and Isma’il raised foundations of the House (with this prayer): ‘’Our Lord: accept (this service) from us: for Thou art All-Hearing, the All-Knowing’’ (Al Baqarah: 127)   

The prayer to make them and their progenies submit to the Will of Allah (SwT) in other words make them Muslims followed:

‘Our Lord! Make of us Muslims bowing to Thy (Will) and our progeny a people Muslim, bowing to They (Will) and show us our places for the celebration of (due) rites; and then turn unto us (in Mercy): for Thou art Oft-Relenting, Most-Merciful’ (Al Baqarah: 128)  

And finally the prayers for the advent of Prophet Muhammad (pbuh) followed the prayer to accept their services and make them and their progenies submit to the Will of Allah (SwT):

"Our Lord! Send among them a Messenger of their own, who shall rehearse Thy Signs to them and instruct them in Scriptures and Wisdom, and purify them: for Thou art the Exalted in Might, the Wise’’ (Al Baqarah: 129) 

With Prophetic foresight, Syedena Ibrahim (A.S) could foresee that Kabbah would descend into a time phase, where the practice of prayer would not follow the precedent, he and his son—Syedena Ismail (A.S) had set, which in essence meant the worship of one and only Allah (SwT) hence not only did the patriarch of prophets—Syedena Ibrahim (A.S) and his son Syedena Ismail (A.S)  pray for making them and making their progenies Muslims, but also prayed for the advent of Messenger—Prophet Muhammad (pbuh) to purify their progenies of corrupt practices and instruct them in Scriptures. 

Allah (SwT) answered their prayers with advent of Prophet Muhammad (pbuh) to renew the pledge of Abrahamic practices.
