وَمَا كَانَ لِنَبِىٍّ أَن يَغُلَّ ۚ وَمَن يَغْلُلْ يَأْتِ بِمَا غَلَّ يَوْمَ ٱلْقِيَٰمَةِ ۚ ثُمَّ تُوَفَّىٰ كُلُّ نَفْسٍۢ مَّا كَسَبَتْ وَهُمْ لَا يُظْلَمُونَ
It is not [attributable] to any prophet that he would act unfaithfully [in regard to war booty]. And whoever betrays, [taking unlawfully], will come with what he took on the Day of Resurrection. Then will every soul be [fully] compensated for what it earned, and they will not be wronged.
And by the mercy of Allah, you dealt with them gently. And had you been severe and harsh-hearted, they would have broken away from about you; so pardon them, and ask forgiveness for them; and consult them in the affairs. Then when you have taken a decision, put your trust in Allah, certainly, Allah loves those who put their trust (in Him)(159)If Allah helps you, none can overcome you; and if He forsakes you, who is there after Him that can help you? And in Allah (Alone) let believers put their trust (160)It is not for any Prophet to illegally take a part of the booty, and whosoever deceives his companions over the booty, he shall bring forth on the Day of Resurrection that which he took. Then every person shall be paid in full what he has earned, and they shall not be dealt with unjustly (161)Is then one who follows (seeks) the pleasure of Allah like the one who draws on himself the wrath of Allah? His abode is Hell, and worse indeed is that destination (162)They are in varying grades with Allah, and Allah is All-Seer of what they do (163)Indeed, Allah conferred a great favor on the believers when He sent among them a Messenger from among themselves, reciting unto them His verses (the Qur'an), and purifying them, and instructing them (in) the Book (the Qur'an) and Al-Hikmah [the wisdom and the Sunnah], while before that they had been in manifest error (164)
Among the Qualities of Our Prophet Muhammad (ﷺ) are Mercy and Kindness
Allah addresses His Messenger ﷺ and reminds him and the believers of the favor that He has made his heart and words soft for his Ummah, those who follow his command and refrain from what he prohibits.
فَبِمَا رَحْمَةٍ مِّنَ اللَّهِ لِنتَ لَهُمْ
(And by the mercy of Allah, you dealt with them gently)[3:159]. meaning, who would have made you this kind, if it was not Allah's mercy for you and them. Qatadah said that,
فَبِمَا رَحْمَةٍ مِّنَ اللَّهِ لِنتَ لَهُمْ
(And by the mercy of Allah, you dealt with them gently) means, "With Allah's mercy you became this kind." Al-Hasan Al-Basri said that this, indeed, is the description of the behavior that Allah sent Muhammad ﷺ with. This Ayah is similar to Allah's statement,
لَقَدْ جَاءَكُمْ رَسُولٌ مِّنْ أَنفُسِكُمْ عَزِيزٌ عَلَيْهِ مَا عَنِتُّمْ حَرِيصٌ عَلَيْكُم بِالْمُؤْمِنِينَ رَءُوفٌ رَّحِيمٌ
(Verily, there has come unto you a Messenger from among yourselves. It grieves him that you should receive any injury or difficulty. He is anxious over you (to be rightly guided, to repent to Allah); for the believers (he is) full of pity, kind, and merciful)[9:128]. Allah said next,
وَلَوْ كُنتَ فَظًّا غَلِيظَ الْقَلْبِ لَانفَضُّوا مِنْ حَوْلِكَ
(And had you been severe and harsh-hearted, they would have broken away from about you;)
The severe person is he who utters harsh words, and,
غَلِيظَ الْقَلْبِ
(harsh-hearted) is the person whose heart is hard. Had this been the Prophet's behavior, "They would have scattered from around you. However, Allah gathered them and made you kind and soft with them, so that their hearts congregate around you." 'Abdullah bin 'Amr said that he read the description of the Messenger of Allah ﷺ in previous Books, "He is not severe, harsh, obscene …
