قَالَ رَسُولُ الله : لَيسَ مِنَّا مَن لاَ يَرحَمُ صَغِيرَنَا وَيُوَقِّرُ كَبِيرَنَا وَيَأمُرُ بِالمَعرُفِ وَيَنهَى عَنِ المُنكَرِ 

The Messenger of Allaah (sallAllaahu `alayhi wa sallam) said,

“Whoever fails to care for our youth, respect our aged, enjoin right, and denounce wrong is not counted among us.” [Imaam Ahmad]

قَالَ رَسُولُ الله : قُلِ الحَقَّ وَإن كَانَ مُرّاً

The Messenger of Allaah (sallAllaahu `alayhi wa sallam) said,

“Speak the truth even though it be bitter.” [Ibn Hibbaan]
