عَنْ أَبِي الحَوْرَاءِ السَّعْدِيِّ قَالَ: قُلْتُ لِلْحَسَنِ بْنِ عَلِيٍّ رضي الله عنهما: مَا حَفِظْتَ مِنْ رَسُولِ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ؟ قَالَ: حَفِظْتُ مِنْ رَسُولِ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «دَعْ مَا يَرِيبُكَ إِلَى مَا لاَ يَرِيبُكَ، فَإِنَّ الصِّدْقَ طُمَأْنِينَةٌ، وَإِنَّ الكَذِبَ رِيبَةٌ».
Kutoka kwa Abul Hauraai Assa'di amesema: Nilisema kumwambia Hassan bin Ally radhi za Allah ziwe juu yao: Ulihifadhi nini kutoka kwa Mtume rehema na amani ziwe juu yake? Akasema: Nilihifadhi kutoka kwa Mtume rehema na amani ziwe juu yake? "Acha linalokutia shaka fanya lisilokutia shaka, kwani ukweli ni utulivu, na bila shaka uongo ni shaka"
Abu al-Hawrā’ as-Sa‘di reported: I said to Al-Hasan ibn ‘Ali (may Allah be pleased with him and his father): What did you memorize from the Messenger of Allah (may Allah's peace and blessings be upon him)? He said: I memorized from the Messenger of Allah (may Allah's peace and blessings be upon him): "Leave what you doubt for what you do not doubt; indeed, truthfulness is tranquility, and lying is doubt."
Muislamu anatakiwa kujenga mambo yake juu ya yakini na kuacha yenye kutia shaka ndani yake, na awe na utambuzi katika dini yake.
Katazo la kutumbukia katika matamanio mabaya.
Ukitaka utulivu na raha achana na mambo yanayokutia shaka na kuyatupilia mbali.
Huruma ya Mwenyezi Mungu kwa waja wake, pale alipowaamrisha katika mambo ambayo ndani yake kuna raha ya moyo, na akawakataza katika yale yanayotia msongo na utata.
