Ibn 'Umar -may Allāh be pleased with him- said:

"Rarely would the Messenger of Allāh (ﷺ) get up from a sitting until he supplicated with these words for his Companions... (and part of this supplication was his saying ﷺ) ((وَلاَ تَجْعَلِ الدُّنْيَا أَكْبَرَ هَمِّنَا، وَلاَ مَبْلَغَ عِلْمِنَا)) “...do not make this Dunya our greatest concern, nor the limit of our knowledge.” [Tirmithi (3502); authenticated by Sheikh Albāni in 'Ṣaḥīḥ At-Tirmithi]
