وَلَقَدْ ءَاتَيْنَآ إِبْرَهِيمَ رُشْدَهُ مِن قَبْلُ وَكُنَّا بِهِ عَـلِمِينَ

(And before, We indeed gave Ibrahim his integrity, and We were indeed most knowledgeable about him)(21:51). Then Allah says:

وَهَدَاهُ إِلَى صِرَطٍ مُّسْتَقِيمٍ

(and guided him to a straight path.) which means to worship Allah alone, without partners or associate, in the manner that He prescribed and which pleases Him.

وَءاتَيْنَـهُ فِى الْدُّنْيَا حَسَنَةً

أَنِ اتَّبِعْ مِلَّةَ إِبْرَهِيمَ حَنِيفًا وَمَا كَانَ مِنَ الْمُشْرِكِينَ

(Follow the religion of Ibrahim (he was a) Hanif and he was not of the idolators.) This is like the Ayah in Surat Al-An`am:

(Say: "Truly, my Lord has guided me to a straight path, a right religion, the religion of Ibrahim, (he was a) Hanif and he was not of the idolators.") (6:161). Then Allah rebukes the Jews,
