I know it feels that we have all been struggling through these long and difficult times, with no solution in sight. However, I hope our world will heal soon. By the grace of The Almighty we will have a new world and environment. Also, our holy Eid al Adha has returned again this year, showing us the true meaning and teaching of self sacrifice. That which Allah has shown to all our Muslim Ummah through the test of Ibrahim (AS). Let us overcome the current crisis situation of the country by dedicating ourselves to this teaching of self sacrifice. Since, our current situation is unexpectedly different from last year, please remember to celebrate this Eid with your own family and friends. It is very wise to stay at our own homes as much as possible, following the safety instructions and maintaining social distancing. To my dearest friends and family a sincere "EID MUBARAK" to you all. May Allah enrich our lives with happiness, peace and prosperity and deliver us quickly from this difficult situation. Have a nice EID Day!
