Cure for all disease.

I just read Solusi magazine (Issue no. 16,2010)  and found these interesting hadith.

Know this, truly in a body, exits a kind of meat, when it is good, the whole body will be good. And when it is bad, the whole body will be damaged. Know this, it is the heart.

Imam al-Tarmizi had quote that a person is still considered a Mukmin if he/she has two characteristics: that is when the person did something good, his/her heart feels happy and when the person did something bad, his/her heart feels uneasy or troubled. This is an indicator that we seek as to determine  whether our heart is still good, sick or weary.

In a hadith by Imam Muslim through a sahabah named Hudzaifah, Rasullullah pbuh told us that there are some hearts of humans that reach a state where it's totally blackened by sins and bad deeds, to the point where they "do not recognize good deeds and do not go against bad deeds, all that they know is whatever been given by their lust/desire." This is a situation where the heart is weary.
