The Messenger of Allah said: "When someone whose religion and character you are pleased with proposes to (someone under the care) of one of you, then marry to him. If you do not do so, then there will be turmoil (Fitnah) in the land and abounding discord (Fasad)."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا خَطَبَ إِلَيْكُمْ مَنْ تَرْضَوْنَ دِينَهُ وَخُلُقَهُ فَزَوِّجُوهُ إِلاَّ تَفْعَلُوا تَكُنْ فِتْنَةٌ فِي الأَرْضِ وَفَسَادٌ عَرِيضٌ قَالَ وَفِي الْبَابِ عَنْ أَبِي حَاتِمٍ الْمُزَنِيِّ وَعَائِشَةَ  

The Messenger of Allah said: "When someone whose religion and character you are pleased with comes to you then marry (her to) him. If you do not do so, then there will be turmoil (Fitnah) in the land and discord (Fasad). If you do not do so, then there will be turmoil (Fitnah) in the land and discord (Fasad)." They said: "O Messenger of Allah! What if there was something about him?" He said: "When someone whose religion and character you are pleased with comes to you then marry him." (And he (pbuh) said this) three times.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا جَاءَكُمْ مَنْ تَرْضَوْنَ دِينَهُ وَخُلُقَهُ فَأَنْكِحُوهُ إِلاَّ تَفْعَلُوا تَكُنْ فِتْنَةٌ فِي الأَرْضِ وَفَسَادٌ قَالُوا يَا رَسُولَ اللَّهِ وَإِنْ كَانَ فِيهِ قَالَ إِذَا جَاءَكُمْ مَنْ تَرْضَوْنَ دِينَهُ وَخُلُقَهُ فَأَنْكِحُوهُ ثَلاَثَ مَرَّاتٍ
