Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings of Allah be upon him) said: "If someone whose character and religion you are pleased with comes to you (with a marriage proposal), then marry (your daughter or ward) to him. If you do not do so, there will be widespread turmoil and corruption on the earth."
