Surah Al Qamar Tafseer

وَنَبِّيْهُمْ أَنَّ الْمَاء قِسْمَةٌ بَيْنَهُمْ

And inform them that the water is to be shared between them,

one day for her to drink and one day for them to drink,

قَالَ هَـذِهِ نَاقَةٌ لَّهَا شِرْبٌ وَلَكُمْ شِرْبُ يَوْمٍ مَّعْلُومٍ

He said:"Here is a she-camel:it has a right to drink, and you have a right to drink (water) on a day, known." (26:155)

Allah's statement,

كُلُّ شِرْبٍ مُّحْتَضَرٌ

each one's right to drink being established.

Mujahid said,

"When she did not drink, they would drink the water, and when she drank, they would drink her milk."

Allah the Exalted said;

فَنَادَوْا صَاحِبَهُمْ فَتَعَاطَى فَعَقَرَ
