At our country, most of people when they are at their old time, they will go pilgrimage at Mecca. After that, their life will be filled with their favourite. Some of them just relax and some of them will play with their grandson. But if they still have some energy, they will do some heavy work such a plants a tree, built some cottage, and what else. Its very different if we see this picture. She is a real granny and maybe have the grandson. At this time, she didn't do as actually like other granny do for example in our country. The title granny didn't make her scared to be one of the combatant of the truth. She has very strong spirit to involve into the Jihad. (an act to struggle for defend Islam from the enemy).
Maybe this granny is strongest than the man because not all man will dare like this. Its show us that's the age actually is not the barrier if we want to do something. If our believe (Iman) is strong, there is no one can stop us for participate at this way. Shame to her if we always make an excuses when there is some Islamic programs, we didn't take part especially for the man.
