عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ مَا قَاتَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَوْمًا حَتَّى يَدْعُوهُمْ
It is narrated from Sayyiduna Abdullah bin Abbas, may Allah be pleased with him, he says: Whenever the Messenger of Allah, peace and blessings be upon him, fought with any people, he first invited them to Islam.
