Abu Hurairah رضي الله عنه reported that the prophet 
said:
"Seven kinds of of people will be sheltered by Allah when there is no shelter but His:
a just Imam (leader);
a young man who grows up worshipping Allah;
a man's whose heart is spiritually attached to mosques;
two men who like each other for Allah's sake- they meet and depart on the same cause ;
a man who says: "No i fear Allah if he is seduced by a woman of social status and beauty;
a man who gives sadaqah (alms giving) so secretly that his left hand would not know what his right hand is doing;
and a man whose eyes water when he secretly glorifies Allah"
(Bukhari and Muslim)
