Opening the verse
وَإِنَّهُۥ لَعِلْمٌ لِّلسَّاعَةِ فَلَا تَمْتَرُنَّ بِهَا وَٱتَّبِعُونِ ۚ هَـٰذَا صِرَٰطٌ مُّسْتَقِيمٌ
And indeed, he [i.e., Jesus] will be [a sign for] knowledge of the Hour, so be not in doubt of it, and follow Me. This is a straight path.
Scholars differ
Scholars differ on "he will be knowledge of the Hour": most say it refers to Isa, whose return is a sign of the Hour; others say it refers to the Qur'an.
