The Prophet ﷺ said, "Avoid the seven destructive sins."The companions asked, "Messenger of Allah, what are they?"He replied, "Associating partners with Allah, practicing magic, killing a soul whom Allah has forbidden to be killed except by right, consuming usury, devouring an orphan's wealth, fleeing from the battlefield, and slandering chaste, believing women who are unaware of any wrongdoing."
عن النبي ﷺ قال: اجتنبوا السبع الموبقات. قالوا: يا رسول الله، وما هن؟ قال: الشرك بالله، والسحر، وقتل النفس التي حرم الله إلا بالحق، وأكل الربا، وأكل مال اليتيم، والتولي يوم الزحف، وقذف المحصنات المؤمنات الغافلات.
Bukhari related it in the Book of Wills (2766), and Muslim in the Book of Faith (89), both through the route of Sulayman bin Bilal, from Thawr bin Zayd Madani, from Abu Ghayth, from Abu Hurairah, as mentioned.As for what has been narrated from Bashir bin Khassasiya Sadusi, who said, "I came to the Prophet ﷺ to give him my pledge of allegiance. He said, he stipulated to me the testimony that there is no god but Allah and that Muhammad is His servant and Messenger, that I establish prayer, pay zakat, perform the hajj of Islam, fast the month of Ramadan, and strive in the cause of Allah. I said, 'Messenger of Allah, there are two things I cannot bear, by Allah, jihad and charity. For they say that whoever turns his back flees battle incurs the wrath of Allah, and I fear that if I am present in such a situation my soul will become greedy and I will hate death. As for charity, by Allah, I have nothing but a small herd and ten camels, which are the mounts and pack animals of my family.' He said, the Messenger of Allah ﷺ then withdrew his hand, moved it, and said, 'Then no jihad and no charity, so how then will you enter paradise?' I said, 'Messenger of Allah, I will give you my pledge.' He said, so I gave him my pledge on all of these conditions."This is gharib (rare/isolated). It was related by Ahmad (21952), Tabarani in Al-Kabir (2/32), Hakim (2/79–80), and Bayhaqi (9/20), all through various routes from Jabala bin Suhaym, from Abu Muthanna Muaththir bin Nafada Kufi, who said, "I heard Bashir bin Khassasiya Sadusi say," and then he related it.Abu Muthanna Muaththir bin Nafada was only deemed reliable by Ibn Hibban and Ajli, and for this reason Hafiz said of him, "Acceptable," meaning when corroborated. I have not found any corroborating narration for him, and there is also something unusual in its wording.
