Wali means Friend of Allah swt (A pious Muslim). The Prophet (s) said in Hadeeth Quddusi that Allah says:
" Whoever shows enmity to a Wali ('protected friend', pious person) of mine, I declare war on him, My slave does not draw near to me with anything more beloved to me than that which I have made compulsory upon him, My slave continues to draw nearer to me with extra (good) deeds (i.e,Nafil), until I love him. When I love him, I am his hearing with which he hears, his sight with which he sees, his hand with which he strikes and his leg by which he walks. and if he asks me, I shall certainly give him. If he seeks refuge in Me, I shall certainly give him refuge (and protection)."
Becoming a Friend of Allah swt is the dream of every Muslim. Is this possible? In this lesson Shaykh Asalam AbuIsmaeel shows to us how we can become the friend of Allah swt.
