فَبَدَأَ بِأَوْعِيَتِهِمْ قَبْلَ وِعَآءِ أَخِيهِ ثُمَّ ٱسْتَخْرَجَهَا مِن وِعَآءِ أَخِيهِ ۚ كَذَٰلِكَ كِدْنَا لِيُوسُفَ ۖ مَا كَانَ لِيَأْخُذَ أَخَاهُ فِى دِينِ ٱلْمَلِكِ إِلَّآ أَن يَشَآءَ ٱللَّهُ ۚ نَرْفَعُ دَرَجَٰتٍۢ مَّن نَّشَآءُ ۗ وَفَوْقَ كُلِّ ذِى عِلْمٍ عَلِيمٌۭ
Then he (Joseph) began the search with their bags before his brother's bag, then he produced it from his brother's bag. Thus did We contrive for Joseph. He could not have taken his brother according to the king's law unless Allah willed. We raise by grades (of mercy) whom We will, and over every lord of knowledge there is one more knowing.
Surah Yusuf(12:76)
Sahih al-Bukhari
Virtues and Merits of the Prophet (pbuh) and his Companions
Chapter: The signs of Prophethood in Islam
Narrated Salim bin Abi Aj-Jad:
Jabir bin `Abdullah said, "The people became very thirsty on the day of Al-Hudaibiya (Treaty). A small pot containing some water was in front of the Prophet (ﷺ) and when he had finished the ablution, the people rushed towards him. He asked, 'What is wrong with you?' They replied, 'We have no water either for performing ablution or for drinking except what is present in front of you.' So he placed his hand in that pot and the water started flowing among his fingers like springs. We all drank and performed ablution (from it)." I asked Jabir, "How many were you?" he replied, "Even if we had been one-hundred-thousand, it would have been sufficient for us, but we were fifteen-hundred."
