Hadith #4

4ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عَبْدِ الله عَنْ عَلِيِّ بْنِ جَعْفَرٍ عَنْ أَخِيهِ أَبِي الْحَسَنِ (عَلَيهِ السَّلام) قَالَ سَمِعْتُهُ يَقُولُ مَنْ قَصَدَ إِلَيْهِ رَجُلٌ مِنْ إِخْوَانِهِ مُسْتَجِيراً بِهِ فِي بَعْضِ أَحْوَالِهِ فَلَمْ يُجِرْهُ بَعْدَ أَنْ يَقْدِرَ عَلَيْهِ فَقَدْ قَطَعَ وَلايَةَ الله عَزَّ وَجَلَّ.

4. Al-Husayn ibn Muhammad has narrated from Mu’alla ibn Muhammad from Ahmad ibn Muhammad ibn ‘Abd Allah from Ali ibn la’ far from his brother abu al-Hassan (a.s.) who has said the following: “I heard abu al-Hassan (a.s.) saying, ‘Anyone whose brother (in belief) comes to him for help and support in his affairs and one does not provide any support or assistance when capable of doing so, has cut off oneself from the guardianship of Allah, the Most Majestic, the Most Holy.’”
