Hadith 13763- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ اللهِ عَنْ إِبْرَاهِيمَ بْنِ مُحَمَّدٍ الْهَمَذَانِيِّ قَالَ كَتَبْتُ إِلَى أَبِي جَعْفَرٍ (عَلَيْهِ السَّلام) فِي التَّزْوِيجِ فَأَتَانِي كِتَابُهُ بِخَطِّهِ قَالَ رَسُولُ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) إِذَا جَاءَكُمْ مَنْ تَرْضَوْنَ خُلُقَهُ وَدِينَهُ فَزَوِّجُوهُ إِلا تَفْعَلُوهُ تَكُنْ فِتْنَةٌ فِي الأرْضِ وَفَسادٌ كَبِيرٌ.
3. A number of our people have narrated from Ahmad Ibn Abdillah from Ibrahim Ibn Muhammad al-Hamadani who has said: “I once wrote to Abu Ja‘far (al-Jawad) (as) about marriage, then his letter came to me with his own handwriting that said, 'Rasulullah (saw) said: If one proposes to you and you are happy with his moral character and religion, then you should marry him. If you do not do so mischief and vast corruption will take place in the land.'"
