The word(s) "sin" appears 346 time(s) in 329 verse(s) in Quran in Abdullah Yusuf Ali translation.

(161) Verily, this brotherhood of yours is a single brotherhood, and I am your Lord and Cherisher: therefore serve Me (and no other).

(162) That (is so). And if one has retaliated to no greater extent than the injury he received, and is again set upon inordinately, Allah will help him: for Allah is One that blots out (sins) and forgives (again and again).

(163) And strive in His cause as ye ought to strive, (with sincerity and under discipline). He has chosen you, and has imposed no difficulties on you in religion; it is the cult of your father Abraham. It is He Who has named you Muslims, both before and in this (Revelation); that the Messenger may be a witness for you, and ye be witnesses for mankind! So establish regular Prayer, give regular Charity, and hold fast to Allah! He is your Protector - the Best to protect and the Best to help!

(164) Also a tree springing out of Mount sinai, which produces oil, and relish for those who use it for food.

(165) And say: "O my Lord! enable me to disembark with thy blessing: for Thou art the Best to enable (us) to disembark."

(166) And verily this Brotherhood of yours is a single Brotherhood, and I am your Lord and Cherisher: therefore fear Me (and no other).

(167) Those who brought forward the lie are a body among yourselves: think it not to be an evil to you; On the contrary it is good for you: to every man among them (will come the punishment) of the sin that he earned, and to him who took on himself the lead among them, will be a penalty grievous.

(168) Marry those among you who are single, or the virtuous ones among yourselves, male or female: if they are in poverty, Allah will give them means out of His grace: for Allah encompasseth all, and he knoweth all things.

(169) It is no fault in the blind nor in one born lame, nor in one afflicted with illness, nor in yourselves, that ye should eat in your own houses, or those of your fathers, or your mothers, or your brothers, or your sisters, or your father's brothers or your father's sisters, or your mother's brothers, or your mother's sisters, or in houses of which the keys are in your possession, or in the house of a sincere friend of yours: there is no blame on you, whether ye eat in company or separately. But if ye enter houses, salute each other - a greeting of blessing and purity as from Allah. Thus does Allah make clear the signs to you: that ye may understand.

(170) Only those are believers, who believe in Allah and His Messenger: when they are with him on a matter requiring collective action, they do not depart until they have asked for his leave; those who ask for thy leave are those who believe in Allah and His Messenger; so when they ask for thy leave, for some business of theirs, give leave to those of them whom thou wilt, and ask Allah for their forgiveness: for Allah is Oft-Forgiving, Most Merciful.
