Nay, seek (God's) help with patient perseverance and prayer: It is indeed hard, except to those who bring a lowly spirit,- (2:45)

Of their goods, take alms, that so thou mightest purify and sanctify them; and pray on their behalf. Verily thy prayers are a source of security for them: And God is One Who heareth and knoweth. (9:103)

And in the hour of early dawn, they (were found) praying for Forgiveness; (51:18)

Not so those devoted to Prayer;- (70:22)

Those who remain steadfast to their prayer; (70:23)

So he gave nothing in charity, nor did he pray!- (75:31)

A votary when he (turns) to pray? (96:10)

Therefore to thy Lord turn in Prayer and Sacrifice. (108:2)
