Or is he not informed with what is in the Suhuf of Musa. And of Ibrahim who fulfilled,
Sa`id bin Jubayr and Ath-Thawri said it means;
"Conveyed all that he was ordered to convey."
Ibn `Abbas said about;
وَفَّى
(fulfilled) ,
"He delivered all that Allah ordered him to deliver."
Sa`id bin Jubayr said about;
وَفَّى
(fulfilled), "What he was ordered."
Qatadah said about;
وَفَّى
(fulfilled),
"He obeyed Allah and delivered His Message to His creatures."
This is the view preferred by Ibn Jarir because it includes the statement before it and supports it.
Allah said,
وَإِذِ ابْتَلَى إِبْرَهِيمَ رَبُّهُ بِكَلِمَـتٍ فَأَتَمَّهُنَّ قَالَ إِنِّى جَـعِلُكَ لِلنَّاسِ إِمَامًا
And (remember) when the Lord of Ibrahim tried him with (certain) commands, which he fulfilled. He said;"Verily, I am going to make you an Imam (a leader) for mankind." (2;124)
Therefore, Ibrahim fulfilled all the commands of his Lord, stayed away from all the prohibitions, and conveyed Allah's Message in its entirety. Therefore, he is worthy of being made a leader for mankind in all of his affairs, statements and actions.
Allah the Exalted said,
ثُمَّ أَوْحَيْنَأ إِلَيْكَ أَنِ اتَّبِعْ مِلَّةَ إِبْرَهِيمَ حَنِيفًا وَمَا كَانَ مِنَ الْمُشْرِكِينَ
Then, We have sent the revelation to you (saying);"Follow the religion of Ibrahim, a Hanif, and he was not of the idolators." (16;123)
None shall carry the Burden of Any Other on the Day of Resurrection
Allah the Exalted explained what He has revealed in the Scripture of Ibrahim and Musa,
أَلاَّ تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَى
