Abu Hurairah رضي الله عنه on his death bed

أن أبا هريرة بكى في مرضه : فقيل : ما يبكيك ؟ قال : ما أبكي على دنياكم هذه ، ولكن على بعد سفري ، وقلة زادي ، وأني أمسيت في صعود ، ومهبطه على جنة أو نار ، فلا أدري أيهما يؤخذ بي

سير أعلام النبلاء

Abu Hurairah رحمة الله عليه began to cry as he was on his deathbed:

It was said to him: what makes you cry?

He said: I am not crying over this transit world of yours. Rather I am crying over my long journey and lack of provisions (for the journey). And what awaits me in descending to paradise or fire, and I know not which one of them will take me.

Why Umar رضي الله عنه had lines on his face

كان في وجه عمر بن الخطاب خطان أسودان من البكاء

حلية الأولياء

Umar رضي الله عنه used to have two black lines on his face due to his crying.
