And (there is) no blame upon you in what you hint [with it] of marriage proposal [to] the women or you conceal it in yourselves. Knows Allah that you will mention them, [and] but (do) not promise them (widows) secretly except that you say a saying honorable. And (do) not resolve (on) the knot (of) marriage until reaches the prescribed term its end. And know that Allah knows what (is) within yourselves so beware of Him. And know that Allah (is) Oft-Forgiving, Most Forbearing.

And those who (are) patient, seeking (the) Face (of) their Lord and establish the prayer and spend from what We have provided them, secretly and publicly and they repel with the good the evil - those for them (is) the final attainment (of) the Home -

Say to My slaves those who believe (to) establish the prayers, and (to) spend from what We have provided them, secretly and publicly, from before [that] comes a Day not any trade in it and not any friendship.
16:75
sets forth Allah the example (of) a slave (who is) owned, not he has power on anything and (one) whom We provided him from Us a provision good, so he spends from it, secretly and publicly. Can they be equal? All praise (is) for Allah! Nay, but most of them (do) not know.
35:29
Indeed, those who recite (the) Book (of) Allah, and establish the prayer and spend out of what We have provided them, secretly and openly, hope (for) a commerce - never it will perish.
