It is narrated from Sayyiduna Suhayb (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever fixes a dowry (mahr) for a woman while intending not to pay it to her will meet Allah, the Mighty and Majestic, as a fornicator. And whoever takes a loan while intending not to repay it will meet Allah as a thief."
