Al-Imâm ibn al-Jawzi, may Allâh have mercy upon him, was once asked:
“Is it better for me to make tasbîh or to make istighfâr?” He replied, “The dirty robe is more in need of soap than perfume.”
Hasan, may Allâh be pleased with him, once said:
“Increase in making istighfâr for you’ll never know when His Mercy will next descend.”
