Oh Allah! Make useful for me what you have taught me and teach me knowledge that will be useful to me. Oh Allah! I ask you for the understanding of the prophets and the memory of the messengers, and those nearest to you. Oh Allah! Make my tongue full of your remembrance and my heart with consciousness of you. Oh Allah! You do whatever you wish, and you are my availer and protector and best of aid.”
