عَنْ حُذَيْفَةَ بْنِ الْيَمَانِ رَضِيَ اللَّه عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: لاَ تَقُولُوا: مَا شَاءَ اللَّهُ وَشَاءَ فُلاَنٌ، وَلَكِنْ قُولُوا: مَا شَاءَ اللَّهُ، ثُمَّ شَاءَ فُلاَنٌ . رَوَاهُ أَبُو دَاوُدَ بِإِسْنَادٍ صَحِيح
Hudhaifah bin Yaman (May Allah be pleased with him) said: The Prophet (ﷺ) said, "Say not: 'What Allah wills and so-and-so wills', but say: 'What Allah wills, and then what so-and-so wills."' [Abu Dawud with authentic Isnad].
