Robbers and Non-Charity givers - Limited time before Judgement Day!
I was with the Messenger of Allah (may the blessings and peace of Allah be upon him) and there came to him two men: one of them was complaining of penury (being very poor), while the other was complaining of brigandry (robbery). The Messenger of Allah (may the blessings and peace of Allah be upon him) said: As for brigandry, it will be but a short time before a caravan will [be able to] go out of Mecca without a guard. As for penury, the Hour (Day of Judgement) will not arrive before one of you takes his charity around without finding anyone to accept it from him. Then (*) one of you will surely stand before Allah, there being no screed between Him and him, nor an interpreter to translate for him. Then He will say to him: Did I not bring you wealth? And he will say: Yes. Then He will say: Did I not send to you a messenger? And he will say: Yes. And he will look to his right and will see nothing but Hell-fire, then he will look to his left and will see nothing but Hell-fire, so let each of you protect himself against Hell-fire, be it with even half a date - and if he finds it not, then with a kind word.
(*) i.e. at the time of the Hour.
