The word(s) "adhere" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) 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 Apostle and the believers; and Allah is aware of what you do.

(2) And enjoin prayer on your followers, and steadily adhere to it; We do not ask you for subsistence; We do give you subsistence, and the (good) end is for guarding (against evil).

(3) He had well-nigh led us astray from our gods had we not adhered to them patiently! And they will know, when they see the punishment, who is straying farther off from the path.

(4) And the chief persons of them break forth, saying: Go and steadily adhere to your gods; this is most surely a thing sought after.
