Abu Huraira reported: The Messenger of Allah, peace be upon him, said, “Verily, my fountain is wider than the distance between Ayla and Eden. Its water is whiter than ice and sweeter than honey and milk. Its cups are more numerous than the stars. Verily, I will prevent some people from it just as a man prevents camels from his fountain.” They said, “O Messenger of Allah, will you recognize us on that Day?” He said, “Yes, you will have marks which nobody among the people will have but you. You will come to me with a blazing forehead and bright hands and feet because of the traces of ablution.”
[Sahih Muslim, Book 2, Number 479]
عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ حَوْضِي أَبْعَدُ مِنْ أَيْلَةَ مِنْ عَدَنٍ لَهُوَ أَشَدُّ بَيَاضًا مِنْ الثَّلْجِ وَأَحْلَى مِنْ الْعَسَلِ بِاللَّبَنِ وَلَآنِيَتُهُ أَكْثَرُ مِنْ عَدَدِ النُّجُومِ وَإِنِّي لَأَصُدُّ النَّاسَ عَنْهُ كَمَا يَصُدُّ الرَّجُلُ إِبِلَ النَّاسِ عَنْ حَوْضِهِ قَالُوا يَا رَسُولَ اللَّهِ أَتَعْرِفُنَا يَوْمَئِذٍ قَالَ نَعَمْ لَكُمْ سِيمَا لَيْسَتْ لِأَحَدٍ مِنْ الْأُمَمِ تَرِدُونَ عَلَيَّ غُرًّا مُحَجَّلِينَ مِنْ أَثَرِ الْوُضُوءِ
247 صحيح مسلم كتاب الطهارة باب استحباب إطالة الغرة والتحجيل في الوضوء
Simple Islamic teaching that most of the people these days forget to apply: Saying "Thank you" or "Jazak Allah Khair ". If someone helps you with something just say this simple sentence with a smile on your face wallahi it creates an atmosphere of peace and friendliness more than you can imagine.
“Whoever does not give thanks to the people does not give thanks to Allaah” (a saheeh hadeeth narrated by Imaam Ahmad, 2/258).
