Do you know who is the bankrupt?

Abu Hurairah (R.A.) reported: Messenger of Allah (SALLALAHO ALAYHE WA ALEHI WASSALAM) said, "Do you know who is the bankrupt?'' They said: "The bankrupt among us is one who has neither money with him nor any property". He said, "The real bankrupt of my Ummah would be he who would come on the Day of Resurrection with Salat, Saum and Sadaqah (charity), (but he will find himself bankrupt on that day as he will have exhausted the good deeds) because he reviled others, brought calumny against others, unlawfully devoured the wealth of others, shed the blood of others and beat others; so his good deeds would be credited to the account of those (who suffered at his hand). If his good deeds fall short to clear the account, their sins would be entered in his account and he would be thrown in the (Hell) Fire." [Muslim].

Abu Musa Al-Ash`ari (R.A.) reported: I asked the Messenger of Allah (SALLALAHO ALAYHE WA ALEHI WASSALAM): "Who is the most excellent among the Muslims?'' He said, "One from whose tongue and hands the other Muslims are secure.'' [Al-Bukhari and Muslim]. 

Sahl bin Sa`d (R.A.) reported: The Messenger of Allah (SALLALAHO ALAYHE WA ALEHI WASSALAM) said, "Whosoever gives me a guarantee to safeguard what is between his jaws and what is between his legs, I shall guarantee him Jannah.'' [Al-Bukhari].
