Wahab bin Munabbih (rahimahullah) says:
After Hazrat Abdullah bin Abbaas (radhiyallahu ‘anhuma) became blind (in his old age), I once led him to the Haram Shareef in Makkah Mukarramah, where he heard a group of people arguing among themselves. He asked me to lead him to them.
On coming to them, he greeted them with “Assalaamu Alaikum”. They requested him to sit down, but he refused and said, “May I tell you about the people who hold a high position in the sight of Allah Ta‘ala? They are those whom Allah’s fear has caused to remain silent, even though they are neither helpless nor dumb. In fact, they are able to speak very well and have a good understanding. However, the zikr of Allah Ta‘ala has over-powered them on account of which they do not speak much. When they are overcome by the deep remembrance of Allah Ta‘ala, then they hasten towards good deeds. Why have you turned away from the path of these people?”
Hazrat Wahab bin Munabbih (rahimahullah) says, “After this admonition, I never even saw a group of two people sitting together in the Haram Shareef (and engaging in worldly conversation).”
It is said that Hazrat Ibnu Abbaas (radhiyallahu ‘anhuma) used to weep so much with Allah Ta‘ala’s fear that the tears flowing down his cheeks had left marks on them.
In this incident, Hazrat Abdullah bin Abbaas (radhiyallahu ‘anhuma) has shown a very easy way to do good deeds. This is to ponder and think about the greatness of Allah Ta‘ala. If this is done, it becomes very easy to do all other good actions with sincerity. Is it so difficult to spend a few minutes, out of the twenty-four hours of a day, to think about the greatness of Allah Ta‘ala?
