2:189They ask you about the crescents. Say, “They are timetables for people, and for the Hajj.” It is not virtuous that you approach homes from their backs, but virtue is to be pious. So approach homes from their doors, and observe God, that you may succeed.

2:196And carry out the Hajj and the Umrah for God. But if you are prevented, then whatever is feasible of offerings. And do not shave your heads until the offering has reached its destination. Whoever of you is sick, or has an injury of the head, then redemption of fasting, or charity, or worship. When you are secure: whoever continues the Umrah until the Hajj, then whatever is feasible of offering. But if he lacks the means, then fasting for three days during the Hajj and seven when you have returned, making ten in all. This is for he whose household is not present at the Sacred Mosque. And remain conscious of God, and know that God is stern in retribution.

2:197The Hajj is during specific months. Whoever decides to perform the Hajj—there shall be no sexual relations, nor misconduct, nor quarrelling during the Hajj. And whatever good you do, God knows it. And take provisions, but the best provision is righteousness. And be mindful of Me, O people of understanding.
