Yahya related to me from Malik from Salih ibn Kaysan from Ubaydullah ibn Abdullah ibn Utba ibn Masud that Zayd ibn Khalid al- Juhani said, "The Messenger of Allah ﷺ took the subh prayer with us at Hudaybiyya after it had rained in the night. When he had finished he went up to the people and said, 'Do you know what your Lord has said?' They said, 'Allah and His Messenger know best.' He said, 'Some of my slaves have begun the morning believing in Me, and others have begun it rejecting Me. As for those who say, 'We were rained on by the overflowing favour of Allah and His mercy,' they believe in Me and reject the stars. But as for those who say, 'We were rained on by such and such a star, they reject Me and believe in the stars.' "  

أَنَّهُ قَالَ صَلَّى لَنَا رَسُولُ اللَّهِ ﷺ صَلاَةَ الصُّبْحِ بِالْحُدَيْبِيَةِ عَلَى إِثْرِ سَمَاءٍ كَانَتْ مِنَ اللَّيْلِ فَلَمَّا انْصَرَفَ أَقْبَلَ عَلَى النَّاسِ فَقَالَ أَتَدْرُونَ مَاذَا قَالَ رَبُّكُمْ قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ قَالَ أَصْبَحَ مِنْ عِبَادِي مُؤْمِنٌ بِي وَكَافِرٌ بِي فَأَمَّا مَنْ قَالَ مُطِرْنَا بِفَضْلِ اللَّهِ وَرَحْمَتِهِ فَذَلِكَ مُؤْمِنٌ بِي كَافِرٌ بِالْكَوْكَبِ وَأَمَّا مَنْ قَالَ مُطِرْنَا بِنَوْءِ كَذَا وَكَذَا فَذَلِكَ كَافِرٌ بِي مُؤْمِنٌ بِالْكَوْكَبِ  

Yahya related to me from Malik that he had heard that the Messenger of Allah ﷺ used to say, "When a cloud appears from the direction of the sea and then goes towards ash-Sham, it will be an abundant source of rain."  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَقُولُ إِذَا أَنْشَأَتْ بَحْرِيَّةً ثُمَّ تَشَاءَمَتْ فَتِلْكَ عَيْنٌ غُدَيْقَةٌ  

Yahya related to me from Malik that he had heard that Abu Hurayra used to say, when morning came after it had rained on the people, "We have been rained upon by the rain of Allah's opening," and would then recite the ayat, "Whatever Allah opens to man of His mercy no-one can withhold, and whatever He withholds no-one can send forward after Him. " (Sura 35 ayat 2).  

أَنَّ أَبَا هُرَيْرَةَ كَانَ يَقُولُ إِذَا أَصْبَحَ وَقَدْ مُطِرَ النَّاسُ مُطِرْنَا بِنَوْءِ الْفَتْحِ ثُمَّ يَتْلُو هَذِهِ الآيَةَ مَا يَفْتَحِ اللَّهُ لِلنَّاسِ مِنْ رَحْمَةٍ فَلاَ مُمْسِكَ لَهَا وَمَا يُمْسِكْ فَلاَ مُرْسِلَ لَهُ مِنْ بَعْدِهِ
