(Al Jinn) 72 : 16
وَأَنْ لَوِ اسْتَقَامُوا عَلَى الطَّرِيقَةِ لَأَسْقَيْنَاهُمْ مَاءً غَدَقًا
And if they are remaining steadfastly upon the path, surely We will make them drink water abundantly.
That means if they are existing as Muslims by submitting all to Allah, they would have got water and other sustenance abundantly. See explanation 7: 96; 39: 7; and 71: 11-13.
