Messenger of Allah ﷺ said, "We (Muslims) are the last (people to come in the world) but (will be) the foremost (on the Day of Resurrection)."  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ نَحْنُ الآخِرُونَ السَّابِقُونَ  

"You should not pass urine in stagnant water which is not flowing then (you may need to) wash in it."  

لاَ يَبُولَنَّ أَحَدُكُمْ فِي الْمَاءِ الدَّائِمِ الَّذِي لاَ يَجْرِي ثُمَّ يَغْتَسِلُ فِيهِ
