The Command to warn His Tribe of near Kindred

Here Allah commands (His Prophet ) to worship Him alone, with no partner or associate, and tells him that whoever associates others in worship with Him, He will punish them. Then Allah commands His Messenger to warn his tribe of near kindred, i.e., those who were most closely related to him, and to tell them that nothing could save any of them except for faith in Allah. Allah also commanded him to be kind and gentle with the believing servants of Allah who followed him, and to disown those who disobeyed him, no matter who they were. Allah said:

فَإِنْ عَصَوْكَ فَقُلْ إِنِّى بَرِىءٌ مِّمَّا تَعْمَلُونَ

وَأَنذِرْ‌ عَشِيرَ‌تَكَ الْأَقْرَ‌بِينَ ﴿214﴾

And warn the nearest people of your clan, -26:214.
