Hadith 517000
Chapter 50: The Evil Eye - كتاب العين
وَحَدَّثَنِي مَالِكٌ، عَنْ مُحَمَّدِ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي صَعْصَعَةَ، أَنَّهُ قَالَ سَمِعْتُ أَبَا الْحُبَابِ، سَعِيدَ بْنَ يَسَارٍ يَقُولُ سَمِعْتُ أَبَا هُرَيْرَةَ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ يُرِدِ اللَّهُ بِهِ خَيْرًا يُصِبْ مِنْهُ " .
Yahya related to me from Malik that Muhammad ibn Abdullah ibn Abi Sasaca said that he heard Abu'l-Hubab Said ibn Yasar say that he had heard Abu Hurayra say, "The Messenger of Allah, may Allah bless him and grant him peace, said, 'Allah afflicts the one for whom He desires good.'"
