قال شيخ الإسلام ابن تيمية :
فمن أحسّ بتقصير في قوله أو عمله أو
حاله أو رزقه أو تقلّب قلب: فعليه بالتوحيد والاستغفار ففيهما الشفاء”. ”
الفتاوى 698/11
Shaykh Al-Islaam Ibn Taymiyyah said:
“So
whoever perceives (from himself) deficiency (shortcomings) in his speech or
actions or his condition or his sustenance or a change of heart, then he should
holdfast to tawheed and seeking forgiveness, for in them is the cure.”
Al-Fataawaa 11/698.
