Leading an Abstemious Life and refraining from the Doubtful
وَعَنْ وَابِصَةَ بْنِ مَعْبَدٍ رَضِيَ اللهُ عَنْهُ قَالَ: أَتَيْت رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ فَقَالَ: “جِئْتَ تَسْأَلُ عَنْ الْبِرِّ؟” قُلْت نَعَمْ، فقَالَ: "استفت قلبك الْبِرُّ مَا اطْمَأَنَّتْ إلَيْهِ النَّفْسُ، وَاطْمَأَنَّ إلَيْهِ الْقَلْبُ، وَالْإِثْمُ مَا حَاكَ فى النَّفْسِ وَتَرَدَّدَ فىالصدر، وَإِنْ أَفْتَاك النَّاسُ وَأَفْتَوْك” ((حَدِيثٌ حَسَنٌ، رَوَاهُ أحمد والدارمي فى مسنديهما)).
Wabisah bin Ma'bad (May Allah be pleased with him) reported: I went to Messenger of Allah (ﷺ) and he asked me, "Have you come to inquire about piety?" I replied in the affirmative. Then he said, "Ask your heart regarding it. Piety is that which contents the soul and comforts the heart, and sin is that which causes doubts and perturbs the heart, even if people pronounce it lawful and give you verdicts on such matters again and again." [Ahmad and Ad- Darmi].
