قَالَ ٱلْمَلَأُ ٱلَّذِينَ كَفَرُوا۟ مِن قَوْمِهِۦٓ إِنَّا لَنَرَىٰكَ فِى سَفَاهَةٍۢ وَإِنَّا لَنَظُنُّكَ مِنَ ٱلْكَٰذِبِينَ
The chieftains of his people, who were disbelieving, said: Lo! we surely see thee in foolishness, and lo! we deem thee of the liars.

Chapter: The superiority of a person suffering from epilepsy
Narrated 'Ata bin Abi Rabah:
Ibn `Abbas said to me, "Shall I show you a woman of the people of Paradise?" I said, "Yes." He said, "This black lady came to the Prophet (ﷺ) and said, 'I get attacks of epilepsy and my body becomes uncovered; please invoke Allah for me.' The Prophet (ﷺ) said (to her), 'If you wish, be patient and you will have (enter) Paradise; and if you wish, I will invoke Allah to cure you.' She said, 'I will remain patient,' and added, 'but I become uncovered, so please invoke Allah for me that I may not become uncovered.' So he invoked Allah for her." Narrated 'Ata: That he had seen Um Zafar, the tall black lady, at (holding) the curtain of the Ka`ba.
