We ask Allaah to make you steadfast in doing good and to make you successful and wise. The most important advice we can give you is:
1-To fear Allaah in private and in public, when coming in and going out, and in all your affairs.
2-Do the best that you can in your work, for Allaah loves when anyone does something for him to do it well. [Hadeeth narrated by al-Bayhaqi in Shu’ab al-Eemaan, and classed as hasan by al-Albaani in Saheeh al-Jaami’].
3-Intend when doing your work to benefit people and help them, and seek to use the halaal money that you will earn after you graduate in ways that will please Allaah.
4-Give sincere advice to the students you will meet, and do not underestimate the impact that a sincere word may have, for how many of those who repent and become devout and righteous took the first step on that path because of a single word.
5-Carry some useful pamphlets, booklets and tapes with you, and give them to your colleagues and the people who are studying with you, so as to spread your goodness and increase your reward.
6-Make a lot of du’aa’, asking Allaah to guide you, for there is no strength, no power and no success, except with Allaah.
And Allaah knows best.
