"And the Messenger of Allah said to them," meaning Salih (peace be upon him): "The she-camel of Allah and her drink" [Al-Shams: 13]. That is: fear regarding the she-camel of Allah, do not touch her with harm, and fear regarding her drink, do not prevent her from it.
﴿فَقَالَ لَهُم رَسُول الله﴾ صَالِحٌ عليه السلام: ﴿نَاقَةَ اللَّهِ وسقياها﴾ أَيْ: اتَّقُوا نَاقَةَ اللَّهِ لَا تمسوها بِسوء وَاتَّقوا (سقياها) شربهَا لَا تمنعوها مِنْهُ
