٥- عَنْهُ عَنْ مُحَمَّدِ بْنِ عَلِيٍّ عَنْ هَارُونَ بْنِ حَمْزَةَ عَنْ عَلِيِّ بْنِ عَبْدِ الْعَزِيزِ قَالَ قَالَ لِي أَبُو عَبْدِ اللهِ (عَلَيْهِ السَّلام) مَا فَعَلَ عُمَرُ بْنُ مُسْلِمٍ قُلْتُ جُعِلْتُ فِدَاكَ أَقْبَلَ عَلَى الْعِبَادَةِ وَتَرَكَ التِّجَارَةَ فَقَالَ وَيْحَهُ أَمَا عَلِمَ أَنَّ تَارِكَ الطَّلَبِ لا يُسْتَجَابُ لَهُ إِنَّ قَوْماً مِنْ أَصْحَابِ رَسُولِ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) لَمَّا نَزَلَتْ وَمَنْ يَتَّقِ اللهَ يَجْعَلْ لَهُ مَخْرَجاً وَيَرْزُقْهُ مِنْ حَيْثُ لا يَحْتَسِبُ أَغْلَقُوا الأبْوَابَ وَأَقْبَلُوا عَلَى الْعِبَادَةِ وَقَالُوا قَدْ كُفِينَا فَبَلَغَ ذَلِكَ النَّبِيَّ (صَلَّى اللهُ عَلَيْهِ وَآلِه) فَأَرْسَلَ إِلَيْهِمْ فَقَالَ مَا حَمَلَكُمْ عَلَى مَا صَنَعْتُمْ قَالُوا يَا رَسُولَ اللهِ تُكُفِّلَ لَنَا بِأَرْزَاقِنَا فَأَقْبَلْنَا عَلَى الْعِبَادَةِ فَقَالَ إِنَّهُ مَنْ فَعَلَ ذَلِكَ لَمْ يُسْتَجَبْ لَهُ عَلَيْكُمْ بِالطَّلَبِ. 
5. It is narrated from him (narrator of previous Hadith) from Muhammad ibn Ali from Harun ibn Hamzah from Ali ibn ‘Abd al-‘Aziz who has said the following: “Abu ‘Abd Allah , once asked me, ‘What has ‘Umar ibn Muslim done?’ I replied, ‘I pray to Allah to keep my soul in service for your cause, ‘he has devoted himself in worship and has given up doing any business.’ He (the Imam) said, ‘Fie upon him! Does he not know that the prayer of one who neglects work to make a living is not answered? A people of the companions of the Messenger of Allah, when this was revealed, “Those who maintain piety before Allah, He makes a way out for them and provides them sustenance from unexpected sources” (66:7), closed their doors and begun to worship. They said, “We have found what we needed.” This was reported to the Holy Prophet who called them in his presence and asked, “What made you do what you had been doing?” They replied, O Messenger of Allah, you guaranteed our sustenance, and thus, we devoted ourselves in worship.” He said, “Whoever does this his prayer is not answered. You must work for your living.’””
