At-Taubah - 9:16

أَمْ حَسِبْتُمْ أَن تُتْرَكُواْ وَلَمَّا يَعْلَمِ اللّهُ الَّذِينَ جَاهَدُواْ مِنكُمْ وَلَمْ يَتَّخِذُواْ مِن دُونِ اللّهِ وَلاَ رَسُولِهِ وَلاَ الْمُؤْمِنِينَ وَلِيجَةً وَاللّهُ خَبِيرٌ بِمَا تَعْمَلُونَ
[9:16]
What! do you think that you will be left alone while Allah has not yet known those of you who have struggled hard and have not taken any one as an adherent besides Allah and His Messenger and the believers; and Allah is aware of what you do.
Or think ye that ye shall be abandoned, as though Allah did not know those among you who strive with might and main, and take none for friends and protectors except Allah, His Messenger, and the (community of) Believers? But Allah is well-acquainted with (all) that ye do.
Or deemed ye that ye would be left (in peace) when Allah yet knoweth not those of you who strive, choosing for familiar none save Allah and His messenger and the believers? Allah is Informed of what ye do.
