Abu Dharr reported God's messenger as saying,
“No Muslim will contribute a pair from every class of property he possesses to be devoted to God’s path without all the guards of paradise meeting him and summoning him to receive what they have.”
Abu Dharr asked him what the nature of that would be, and he replied, “If they are camels there will be two, and if they are cows there will be two.”
When God created the earth it began to oscillate, so He created the mountains, ordered them on to it, and it became steady. The angels marvelled at the strength of the mountains and asked their Lord whether there was anything in His creation stronger than the mountains, to which He replied that iron was stronger.
They asked if anything in His creation was stronger than iron, and He replied that fire was.
They asked if anything in His creation was stronger than fire and He replied that water was.
They asked if anything in His creation was stronger than water and He replied that wind was.
They asked if anything in His creation was stronger than wind and He replied,
“Yes, the son of Adam who gives sadaqa with his right hand concealing it from his left.”
Tirmidhi transmitted it, saying this is a gharib tradition.
Marthad b. ‘Abdallah said one of the companions of God’s messenger told him that he had heard him say,
“The believer's shade on the day of resurrection will be his sadaqa.”
Narrated Abu Dharr reported God's messenger as saying,
“There are three whom God loves and three whom God hates. Those whom God loves are:
a man who, when one came and begged from some people in God’s name, not because of any relationship between him and them, and was refused by them, withdrew from them and gave him something secretly, no one knowing of the gift but God and the one who gave it;
a man who travelled all night with people till sleep was more desirable to them than anything which could be compared with it, and when they laid down their heads got up and engaged in his devotions and recited verses of the Qur’an;
and a man who was in a detachment which met the enemy and was routed, yet went straight forward till he was killed or given victory.
The three whom God hates are an old man who commits fornication, a poor man who is proud, and a rich man who is oppressive.”
Tirmidhi and Nasa’i transmitted it but Nasa'i did not mention the three whom God hates.
