Alaqah came to the Messenger of Allah ﷺ and embraced Islam. He then came back from him and passed some people who had a lunatic fettered in chains. His people said: We are told that your companion has brought some good. Have you something with which you can cure him? I then recited Surat al-Fatihah and he was cured. They gave me one hundred sheep. I then came to the Messenger of Allah ﷺ and informed him of it. He asked: Is it only this? The narrator, Musaddad, said in his other version: Did you say anything other than this? I said: No. He said: Take it, for by my life, some accept if for a worthless chain, but you have done so for a genuine one. (Using translation from Abū Dāʾūd 3896)
أَنَّهُ أَتَى النَّبِيَّ ﷺ ثُمَّ أَقْبَلَ رَاجِعًا مِنْ عِنْدِهِ فَمَرَّ عَلَى قَوْمٍ عِنْدَهُمْ رَجُلٌ مُوثَقٌ بِالْحَدِيدِ فَقَالَ أَهْلُهُ إِنَّهُ قَدْ حُدِّثْنَا أَنَّ مَلِكَكُمْ هَذَا قَدْ جَاءَ بِخَيْرٍ فَهَلْ عِنْدَكَ شَيْءٌ تَرْقِيهِ؟ فَرَقَيْتُهُ بِفَاتِحَةِ الْكِتَابِ فَبَرَأَ فَأَعْطَوْنِي مِائَةَ شَاةٍ فَأَتَيْتُ النَّبِيَّ ﷺ فَقَالَ «خُذْهَا فَلَعَمْرِي لَمَنْ أَكَلَ بِرُقْيَةِ بَاطِلٍ فَقَدْ أَكَلْتَ بِرُقْيَةِ حَقٍّ»
