Hadith

 وَ بِهَذَا اَلْإِسْنَادِ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ صَفْوَانَ اَلْجَمَّالِ عَنْ أَبِي عَبْدِ اَللَّهِ ع قَالَ سَمِعْتُهُ يَقُولُ إِنَّ اَلْمُؤْمِنَ يَخْشَعُ لَهُ كُلُّ شَيْ‌ءٍ ثُمَّ قَالَ ع إِذَا كَانَ مُخْلِصاً قَلْبَهُ لِلَّهِ أَخَافَ اَللَّهُ مِنْهُ كُلَّ شَيْ‌ءٍ حَتَّى هَوَامَّ اَلْأَرْضِ وَ سِبَاعَهَا وَ طَيْرَ اَلسَّمَاءِ.

 (The same previous series of relaters)… from Mohammed bin Ahmed from … Safwan al-Jammal that he heard Abu Abdullah (a) saying: Everything is submissive to the believer. He (a) then added: Allah will cause everything, including vermin, beasts, and birds, to fear the believer if he is sincere to Allah.
