Allah has blessed us with the opportunity to be here, seeking to become a means of guidance (hidayah) for our families, relatives, friends, communities, and the entire Ummah. However, to be effective, we must start with ourselves; we should be the first to benefit from this righteous environment. Our entire deen consists of five main departments: belief (Aqaaid), worship (Ibaadat), dealings (Muamalat), social interactions (Muasharat), and character (Akhlaq). All aspects of our lives and Shariah should conform to the teachings of Allah and the Prophet Muhammad (PBUH).
If we ourselves are weak, not practical, or engaged in sin and disobedience (e.g., neglecting salah or other ibadah), we cannot expect others to heed our advice. It is very important to first put ourselves right.
The speaker gives an example: If we want to advise family members to keep their beards, but we ourselves are shaving or trimming ours, our message will lack impact. Others will question why we aren't practicing what we preach.
Another example is given about a Sahabi (companion of the Prophet) who taught a dua (supplication) for protection from calamities. He himself suffered a stroke. He later clarified that he forgot to recite the dua on the specific day he was afflicted, highlighting the importance of consistent practice.
In conclusion, when we want to advise someone, our own actions need to be correct for it to have a proper impact. If we are not practicing what we are saying, the desired impact may not occur, or there might be no enthusiasm for others to act upon it.
