أَمَّن يَهْدِيكُمْ فِى ظُلُمَٰتِ ٱلْبَرِّ وَٱلْبَحْرِ وَمَن يُرْسِلُ ٱلرِّيَٰحَ بُشْرًۢا بَيْنَ يَدَىْ رَحْمَتِهِۦٓ ۗ أَءِلَٰهٌۭ مَّعَ ٱللَّهِ ۚ تَعَٰلَى ٱللَّهُ عَمَّا يُشْرِكُونَ
Is not He (best) Who guideth you in the darkness of the land and the sea, He Who sendeth the winds as heralds of His mercy? Is there any Allah beside Allah? High Exalted be Allah from all that they ascribe as partner (unto Him)!

Narrated Abu Huraira:
Gabriel came to the Prophet (ﷺ) and said, "O Allah's Messenger (ﷺ)! This is Khadija coming to you with a dish having meat soup (or some food or drink). When she reaches you, greet her on behalf of her Lord (i.e. Allah) and on my behalf, and give her the glad tidings of having a Qasab palace in Paradise wherein there will be neither any noise nor any fatigue (trouble) . "
