What Will Ye Worship After Me?

In the Name of Allah, Most Gracious, Most Merciful. 

Say: He is Allah, the One and Only, 

Allah, the Eternal, Absolute; He begetteth not, 

nor is He begotten; And there is none like unto Him.

Say ye: "We believe in God, and the revelations given to us, and th Abraham, Ismail, Isaac, Jacob, and the tribes, and that given to Moses and Jesus, and that given to (all) Prophets from their Lord: We make no difference between one and another of them and we bow to God (in Islam)"
Sura Al-Baqarah, 2:136

There ye witnesses when death appeared before Jacob? behold, he said to his sons! "What will ye worship after me?" They said: "We shall worship thy God and the God of thy fathers, of Abraham, Ismail and Isaac, the One (True) God: To Him we bow (in Islam)."
Sura Al-Baqarah, 2:133
