The word(s) "forms" appears 13 time(s) in 13 verse(s) in Quran in Mohsin Khan translation.

(11) (And has also sent to you) a Messenger (Muhammad صلى الله عليه وسلم), who recites to you the Verses of Allah (the Qur'an) containing clear explanations, that He may take out those who believe and do righteous good deeds, from the darkness (of polytheism and disbelief) to the light (of Islamic Monotheism). And whosoever believes in Allah and performs righteous good deeds, He will admit him into Gardens under which rivers flow (Paradise) to dwell therein forever. Allah has indeed granted for him an excellent provision.

(12) Except to a Messenger (from mankind) whom He has chosen (He informs him of unseen as much as He likes), and then He makes a band of watching guards (angels) to march before him and behind him.

(13) Indeed he succeeds who purifies his ownself (i.e. obeys and performs all that Allah ordered, by following the true Faith of Islamic Monotheism and by doing righteous good deeds).
