It is reported by Abu wail that someone said to Abu Nuhaylah (when he was ill), "Pray to Allah." So, he made this supplication, "Oh Allah, lessen the illness but do not diminish the reward." He was again asked to supplicate Allah and he said, "O Allah, let me be among the near ones and make my mother among the hoor (maids of Paradise)”.

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، قَالَ: حَدَّثَنَا سُفْيَانُ، عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنْ أَبِي نُحَيْلَةَ، قِيلَ لَهُ: ادْعُ اللَّهَ، قَالَ: اللَّهُمَّ انْقُصْ مِنَ الْمَرَضِ، وَلاَ تَنْقُصْ مِنَ الأَجْرِ، فَقِيلَ لَهُ: ادْعُ، ادْعُ. فَقَالَ: اللَّهُمَّ اجْعَلْنِي مِنَ الْمُقَرَّبِينَ، وَاجْعَلْ أُمِّي مِنَ الْحُورِ الْعِينِ.
