9:84You are never to pray over anyone of them who dies, nor are you to stand at his graveside. They rejected God and His Messenger, and died while they were sinners.

9:87They prefer to be with those who stay behind. Their hearts were sealed, so they do not understand.

9:108Do not stand in it, ever. A mosque founded upon piety from the first day is worthier of your standing in it. In it are men who love to be purified. God loves those who purify themselves.

9:122It is not advisable for the believers to march out altogether. Of every division that marches out, let a group remain behind, to gain understanding of the religion, and to notify their people when they have returned to them, that they may beware.

9:127And whenever a chapter is revealed, they look at one another, “Does anyone see you?” Then they slip away. God has diverted their hearts, because they are a people who do not understand.
