-اَللّٰهُمَّ أَلْهِمْنِيْ رُشْدِيْ
Allaahumma alhimnii rushdii. (‘Imran ibn Husayn. Sunan at-Tirmidhi #3405)
O Allah, inspire me with the right guidance for me.
Ameen
This very profound du’aa demands reflection. A person who is sincerely seeking guidance from Allah Ta’aala has taken the first and the most important step in getting it, since Allah Ta’aala is the source of all guidance. Whenever we are faced with a decision, we should resort to this du’aa. Additionally we can suggest this to a non-Muslim who is in search of the true religion. If he or she sincerely makes this du’aa Allah Ta’aala will open his or her heart to Islam, as has been the experience of numerous new Muslims.
