It is narrated from Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) that he heard the Messenger of Allah (peace and blessings of Allah be upon him) say: Allah, the Mighty and Majestic, says: "I am the Most Merciful (Rahman) and I have created the womb (rahm), and I have derived its name from My Name. Whoever joins it, I will join him, and whoever severs it, I will sever him."
