Ibn `Abbas told that a woman brought a son of hers to God's messenger and said, "Messenger of God, my son is possessed, and it seizes him when we have our morning and evening meals." God's messenger stroked his breast and made a supplication, and when the boy had vomited once, something like a black puppy came running out from within him. Darimi transmitted it.

وَعَنِ ابْنِ عَبَّاسٍ قَالَ: إِنَّ امْرَأَةً جَاءَتْ بابنٍ لَهَا إِلى رَسُول اللَّهِ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَتْ يارسول اللَّهِ إِنَّ ابْنِي بِهِ جُنُونٌ وَأَنَّهُ لَيَأْخُذُهُ عِنْدَ غَدَائِنَا وَعَشَائِنَا (فَيَخْبُثُ عَلَيْنَا) فَمَسَحَ رَسُولُ اللَّهِ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَدْرَهُ وَدَعَا فَثَعَّ ثَعَّةً وَخَرَجَ مِنْ جَوْفِهِ مِثْلُ الجرو الْأسود يسْعَى. رَوَاهُ الدَّارمِيّ
