عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَلْعُونٌ مَنْ سَبَّ أَبَاهُ مَلْعُونٌ مَنْ سَبَّ أُمَّهُ
It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Whoever abuses his father is accursed, and whoever speaks ill of his mother, curse has been invoked upon him.
