Hadith #2

2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ مَا مِنْ مُؤْمِنٍ وَلاَ كَافِرٍ إِلاَّ وَهُوَ يَأْتِي أَهْلَهُ عِنْدَ زَوَالِ الشَّمْسِ فَإِذَا رَأَى أَهْلَهُ يَعْمَلُونَ بِالصَّالِحَاتِ حَمِدَ الله عَلَى ذَلِكَ وَإِذَا رَأَى الْكَافِرُ أَهْلَهُ يَعْمَلُونَ بِالصَّالِحَاتِ كَانَتْ عَلَيْهِ حَسْرَةً.

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Ali ibn abu Hamzah from abu Basir who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that every believing and unbeliever person visits his family everyday just after midday. If he finds his family performing good deeds, he praises and thanks Allah for this. When an unbeliever finds his family in good deeds, he laments and regrets (for his lost opportunities).”
