أَخْبَرَنَا عَبْدُ الْجَبَّارِ بْنُ الْعَلاَءِ، عَنْ سُفْيَانَ، عَنْ عَمْرٍو، عَنْ عَتَّابِ بْنِ حُنَيْنٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
" لَوْ أَمْسَكَ اللَّهُ عَزَّ وَجَلَّ الْمَطَرَ عَنْ عِبَادِهِ خَمْسَ سِنِينَ ثُمَّ أَرْسَلَهُ لأَصْبَحَتْ طَائِفَةٌ مِنَ النَّاسِ كَافِرِينَ يَقُولُونَ سُقِينَا بِنَوْءِ الْمِجْدَحِ " .
“The Messenger of Allah (ﷺ) said: ‘If Allah (SWT) were to withhold rain from His slaves for five years and then send it, some of the people would become disbelievers, saying: “We have been given rain by the star of Al-Mijdah.”
