حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُسَدَّدٌ، - الْمَعْنَى - قَالاَ حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ بْنِ الأَخْنَسِ، عَنِ الْوَلِيدِ بْنِ عَبْدِ اللَّهِ، عَنْ يُوسُفَ بْنِ مَاهَكَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَنِ اقْتَبَسَ عِلْمًا مِنَ النُّجُومِ اقْتَبَسَ شُعْبَةً مِنَ السِّحْرِ زَادَ مَا زَادَ ‏"‏ ‏.‏

Narrated Zaid bin Khalid Al-Juhani

The Messenger of Allah (ﷺ) led us in the morning prayer at al-Hudaibiyyah after rain which has fallen during the night, and when he finished, he turned to the people and said: Do you know what your Lord has said ? They said: Allah and His Apostle know best. He said: This morning there were among mt servants one who believes in me and one who disbelieves. The one who said: "We have been given rain by Allah's grace and mercy" is the one who believes in me and disbelieves in the star ; but the one who said: "We have been given rain by such and such a rain star," is the one who disbelieves in me and believes in the star.
