بسم الله والحمد لله والصلاة والسلام على رسول الله ، وبعد

`Abdullaah Ibn Mubaarak رحمه الله said:

“Among the great calamities which can inflict a person is that he knows that he is negligent (in his religious duties) but he does not mind it nor does he grieve over it.”

[Shu`ab al-Imaan (2/271) of Imaam al-Baihaqee]
