Khalid bin Umayr reported,

Utba bin Ghazwan delivered a sermon to us. He praised Allah and extolled Him, then said,"To proceed. This world has announced its departure and turned away in swift retreat. Nothing remains of it except a last trace, like the final drops at the bottom of a vessel that its owner drains. You are moving from it to an abode that will never pass away, so move on with the best of what is in your hands. We have been told that a stone is cast from the edge of Hell and falls through it for seventy years without reaching its bottom, yet by Allah, it shall be filled. Are you astonished?"… and the hadith continues at length.

Sahih

عن خالد بن عمير العدوي قال

خطبنا عتبة بن غزوان، فحمد الله وأثنى عليه، ثم قال: أما بعد فإن الدنيا قد آذنت بصرم وولت حذاء، ولم يبق منها إلا صبابة كصبابة الإناء، يتصابها صاحبها، وإنكم منتقلون منها إلى دار لا زوال لها، فانتقلوا بخير ما بحضرتكم، فإنه قد ذكر لنا أن الحجر يلقى من شفة جهنم فيهوي فيها سبعين عاما لا يدرك لها قعر، ووالله لتملأن أفعجبتم؟… الحديث بطوله.
