"Contentment is the greatest door that one enters to Allah, it is the source of tranquility for the worshiper and paradise on earth. Whoever does not enter it will not enter the Paradise in the Hereafter."

When [the saints] perform actions to God, then the soul says: 'Oh! that I could do what pleases God!' When they come to suffer any cross: 'Oh, that what God does might please me!' I labour to do what pleases God, and I labour that what God does shall please me: here is a Christian indeed, who shall endeavour both these. It is but one side of a Christian to endeavour to do what pleases God; you must as well endeavour to be pleased with what God does, and so you will come to be a complete Christian when you can do both, and that is the first thing in the excellence of this grace of contentment.
