..he said I was pondering over

عن سفيان قال: كان عمر بن عبد العزيز يوما ساكتا و أصحابه يتحدثون، فقالوا له: مالك لا تتكلم يا أمير المؤمنين؟ قال: كنت مفكرا في أهل الجنة كيف يتزاورون فيها، و في أهل النار كيف يصطرخون فيها. ثم بكى.

سيرة عمر بن عبد العزيز.

One day Umar Abdul Aziz رحمة الله عليه was silent amongst his companions as they were conversing.

So they asked him: ‘Why is it that we do not see you speaking oh Ameer al-Mu’minen.

He replied: ‘I was pondering over the people of Paradise and how they will visit one another. And how the people of Hell will be screaming calling out for help and then he began to cry.
