3- إِبْرَاهِيمُ بْنُ أَبِي الْبِلادِ عَنْ أَبِيهِ عَنْ أَحَدِهِمَا (عَلَيْهِما السَّلام) قَالَ قَالَ رَسُولُ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) يَا أَيُّهَا النَّاسُ إِنَّهُ قَدْ نَفَثَ فِي رُوعِي رُوحُ الْقُدُسِ أَنَّهُ لَنْ تَمُوتَ نَفْسٌ حَتَّى تَسْتَوْفِيَ رِزْقَهَا وَ إِنْ أَبْطَأَ عَلَيْهَا فَاتَّقُوا اللهَ عَزَّ وَجَلَّ وَأَجْمِلُوا فِي الطَّلَبِ وَلا يَحْمِلَنَّكُمُ اسْتِبْطَاءُ شَيْ‏ءٍ مِمَّا عِنْدَ اللهِ عَزَّ وَجَلَّ أَنْ تُصِيبُوهُ بِمَعْصِيَةِ اللهِ فَإِنَّ اللهَ عَزَّ وَجَلَّ لا يُنَالُ مَا عِنْدَهُ إِلا بِالطَّاعَةِ.

3. Ibrahim ibn abu al-Balad has narrated from his father from one of the two Imams, ‘Alayhi al-Salam, who has said the following: “The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘O people, the trustworthy spirit has inspired my understanding that a soul never dies until it completes (depleting of) its sustenance even if it takes place with a certain degree of delays. You must maintain piety before Allah, most Majestic, most Glorious, and seek your sustenance meticulously. You must not allow certain degrees of delays from Allah, most Majestic, most Glorious, to cause you to indulge in Allah’s disobedience. What is with Allah is only achieved through obedience to Him.’”
