Our heart as an advisor

ahmad-zuhd:1768 – ʿAbdullāh from my father > al-Aswad b. ʿĀmir > Ḥammād > Ḥabīb > Ibn Sīrīn

If Allah intends good for His servant, He will provide him with an advisor from his own heart who commands him and prohibits him."  

الزهد لأحمد:١٧٦٨ – حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي أَبِي حَدَّثَنَا الْأَسْوَدُ بْنُ عَامِرٍ حَدَّثَنَا حَمَّادٌ عَنْ حَبِيبٍ عَنِ ابْنِ سِيرِينَ قَالَ

«إِذَا أَرَادَ اللَّهُ بِعَبْدٍ خَيْرًا جَعَلَ لَهُ وَاعِظًا مِنْ قَلْبِهِ يَأْمُرُهُ وَيَنْهَاهُ»
