The word(s) "slip" appears 4 time(s) in 4 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Then did Satan make them slip from the (garden), and get them out of the state (of felicity) in which they had been. We said: "Get ye down, all (ye people), with enmity between yourselves. On earth will be your dwelling-place and your means of livelihood - for a time."

(2) And take not your oaths, to practise deception between yourselves, with the result that someone's foot may slip after it was firmly planted, and ye may have to taste the evil (consequences) of having hindered (men) from the Path of Allah, and a Mighty Wrath descend on you.

(3) "It may be that my Lord will give me something better than thy garden, and that He will send on thy garden thunderbolts (by way of reckoning) from heaven, making it (but) slippery sand!-

(4) Deem not the summons of the Messenger among yourselves like the summons of one of you to another: Allah doth know those of you who slip away under shelter of some excuse: then let those beware who withstand the Messenger's order, lest some trial befall them, or a grievous penalty be inflicted on them.
