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, taking a life that Allah has made sacred except by right, consuming usury, devouring an orphan's wealth, fleeing from the battlefield, and slandering chaste, believing, and unsuspecting women."
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 narrated it in the Chapter on Wills (2766), and Muslim in the Chapter on Faith (89), both through Sulayman bin Bilal, from Thawr bin Zayd, from Abu Ghayth, from Abu Hurairah, who related it.As for what was narrated from Abdullah bin Umar, that he was on one of the military expeditions of the Messenger of Allah ﷺ, he said, "The people scattered in a rush, and I was among those who scattered. When we emerged, we said, 'What shall we do, we have fled from the battle line and brought wrath upon ourselves?' So we said, 'Let us enter Madinah and lie low there, and go about without anyone seeing us.'"He said, "So we entered, and we said, 'What if we presented ourselves to the Messenger of Allah ﷺ? If there is repentance for us, we will stay, and if it is otherwise, we will leave.' So we sat waiting for the Messenger of Allah ﷺ before the Fajr prayer, and when he came out, we stood before him and said, 'We are the ones who fled.' He turned to us and said, 'No, rather you are the ones who returned to the fight.'"He said, "So we drew near and kissed his hand, and he said, 'I am the rallying point of the Muslims.'"This is daif.Abu Dawud (2647), Tirmidhi (1716), Ahmad (5384), and Bukhari in Adab al-Mufrad (972) all narrated it through routes from Yazid bin Abu Ziyad, from Abdul-Rahman bin Abu Layla, from Abdullah bin Umar, who related it. The wording given here is Abu Dawud's.Ibn Majah (3407) narrated it through Yazid, with the same chain, limiting the mention to the kissing only.Yazid bin Abu Ziyad is the Hashimi, their freed client, and he is daif by the agreement of the scholars.His saying, "The people scattered in a rush" (with the letters ha and sad without dots) means they moved about seeking to flee.His saying, "buna" (with damma on the ba, on the pattern of "qulna"), comes from "baa bil-ghadab," meaning he returned bearing it, that is, he incurred it.His saying, "You are the ones who returned to the fight" means those who go back to the fighting and turn towards it.His saying, "your rallying point," the fi'ah is the group that stays behind the army, to which the army takes refuge if defeat befalls them.
