It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him) said: "Marry off righteous men and women." Imam Darimi (may Allah have mercy on him) said: In this hadith, the following part was omitted by me: Whatever comes to them afterwards is good.
Hadith Takhrijاس حدیث کو امام دارمی رحمہ اللہ کے علاوہ کسی نے ذکر نہیں کیا، اس کی سند حسن کے درجہ میں ہے۔
Brief Explanation
(Commentary on Hadith 2217)
Most likely, this hadith is in support of the noble verse: «﴿وَأَنْكِحُواالْأَيَامَىمِنْكُمْوَالصَّالِحِينَمِنْعِبَادِكُمْوَإِمَائِكُمْ﴾ [النور : 32]».
The meaning of this verse is: "Marry off those among you who are single, and also the righteous among your male and female slaves."
In this verse, encouragement to perform marriage (nikah) has been given.
