The major difference between Islam and Christianity is the nature of God that is revealed. One aspect of God that is evident in Christianity is his meekness. This should not be confused with weakness.
The Qur'an speaks of humility. In 3:159, Muhammad is praised for his humility by dealing gently with those whom could have been in rebellion to him.
فَبِمَا رَحْمَةٍ مِّنَ اللَّهِ لِنتَ لَهُمْ ۖ وَلَوْ كُنتَ فَظًّا غَلِيظَ الْقَلْبِ لَانفَضُّوا مِنْ حَوْلِكَ ۖ فَاعْفُ عَنْهُمْ وَاسْتَغْفِرْ لَهُمْ وَشَاوِرْهُمْ فِي الْأَمْرِ ۖ فَإِذَا عَزَمْتَ فَتَوَكَّلْ عَلَى اللَّهِ ۚ إِنَّ اللَّهَ يُحِبُّ الْمُتَوَكِّلِينَ - 3:159
“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”
[Aal ‘Imraan 3:159]
