The word(s) "form" appears 158 time(s) in 149 verse(s) in Quran in Mohsin Khan translation.

(91) Shall I inform you (O people!) upon whom the Shayatin (devils) descend?

(92) Those who perform As-Salat (Iqamat-as-Salat) and give Zakat and they believe with certainty in the Hereafter (resurrection, recompense of their good and bad deeds, Paradise and Hell).

(93) (Remember) when Musa (Moses) said to his household: "Verily I have seen a fire; I will bring you from there some information, or I will bring you a burning brand, that you may warm yourselves."

(94) And there were in the city nine men (from the sons of their chiefs), who made mischief in the land, and would not reform.

(95) Then, when Musa (Moses) had fulfilled the term, and was travelling with his family, he saw a fire in the direction of Tur (Mount). He said to his family: "Wait, I have seen a fire; perhaps I may bring you from there some information, or a burning fire-brand that you may warm yourselves."

(96) Recite (O Muhammad صلى الله عليه وسلم) what has been revealed to you of the Book (the Qur'an), and perform As-Salat (Iqamat-as-Salat). Verily, As-Salat (the prayer) prevents from Al-Fahsha' (i.e. great sins of every kind, unlawful sexual intercourse) and Al-Munkar (i.e. disbelief, polytheism, and every kind of evil wicked deed) and the remembering (praising) of (you by) Allah (in front of the angels) is greater indeed [than your remembering (praising) of Allah in prayers. And Allah knows what you do.

(97) (And remain always) turning in repentance to Him (only), and be afraid and dutiful to Him; and perform As-Salat (Iqamat-as-Salat) and be not of Al-Mushrikun (the polytheists, idolaters, disbelievers in the Oneness of Allah).

(98) Those who perform As-Salat (Iqamat-as-Salat) and give Zakat and they have faith in the Hereafter with certainty.

(99) "O my son! Aqim-As-Salat (perform As-Salat), enjoin (on people) Al-Ma'ruf - (Islamic Monotheism and all that is good), and forbid (people) from Al-Munkar (i.e. disbelief in the Oneness of Allah, polytheism of all kinds and all that is evil and bad), and bear with patience whatever befalls you. Verily, these are some of the important commandments (ordered by Allah with no exemption).

(100) And whosoever submits his face (himself) to Allah, while he is a Muhsin (good-doer i.e. performs good deeds totally for Allah's sake without any show off or to gain praise or fame and does them in accordance with the Sunnah of Allah's Messenger Muhammad صلى الله عليه وسلم), then he has grasped the most trustworthy handhold [La ilaha illallah (none has the right to be worshipped but Allah)]. And to Allah return all matters for decision.
