Mu'adh b. Anas al-Juhani reported God’s Messenger as saying, “If anyone sits in his place of prayer when he finishes the Morning Prayer till he prays the two rak'as of the forenoon, saying nothing but what is good, his sins will be forgiven him even if they are more than the foam of the sea.”
Abu Huraira reported God’s Messenger as saying, “If anyone perseveres in praying the two rak'as of the forenoon, his sins will be forgiven him, even if they are like the foam of the sea.”
Buraida said that he heard God’s Messenger say, “A human being has three hundred and sixty joints for each of which he must give alms.” On being asked who was capable of doing that he replied, “It may be mucus in the mosque which you bury, and something which you remove from the road; but if you do not find such, two rak'as in the forenoon will suffice you.”
