Who believe in the Unseen, are steadfast in prayer, and spend out of what We have provided for them; (2:3)
And be steadfast in prayer; practice regular charity; and bow down your heads with those who bow down (in worship).(2:43)
Nay, seek (Allah’s) help with patient perseverance and prayer: It is indeed hard, except to those who bring a lowly spirit, (2:45)
And be steadfast in prayer and regular in charity: And whatever good ye send forth for your souls before you, ye shall find it with Allah: for Allah sees Well all that ye do.(2:110)
O ye who believe! seek help with patient perseverance and prayer; for Allah is with those who patiently persevere. (2:153)
Guard strictly your (habit of) prayers, especially the Middle Prayer; and stand before Allah in a devout (frame of mind). (2:238)
