The word(s) "suck" appears 7 time(s) in 5 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Prohibited to you (For marriage) are:- Your mothers, daughters, sisters; father's sisters, Mother's sisters; brother's daughters, sister's daughters; foster-mothers (Who gave you suck), foster-sisters; your wives' mothers; your step-daughters under your guardianship, born of your wives to whom ye have gone in,- no prohibition if ye have not gone in;- (Those who have been) wives of your sons proceeding from your loins; and two sisters in wedlock at one and the same time, except for what is past; for Allah is Oft-forgiving, Most Merciful;-

(2) The Day ye shall see it, every mother giving suck shall forget her suckling-babe, and every pregnant female shall drop her load (unformed): thou shalt see mankind as in a drunken riot, yet not drunk: but dreadful will be the Wrath of Allah.

(3) So We sent this inspiration to the mother of Moses: "suckle (thy child), but when thou hast fears about him, cast him into the river, but fear not nor grieve: for We shall restore him to thee, and We shall make him one of Our messengers."

(4) And we ordained that he refused suck at first, until (His sister came up and) said: "Shall I point out to you the people of a house that will nourish and bring him up for you and be sincerely attached to him?"...

(5) Let the women live (in 'iddat) in the same style as ye live, according to your means: Annoy them not, so as to restrict them. And if they carry (life in their wombs), then spend (your substance) on them until they deliver their burden: and if they suckle your (offspring), give them their recompense: and take mutual counsel together, according to what is just and reasonable. And if ye find yourselves in difficulties, let another woman suckle (the child) on the (father's) behalf.
