You can use timers for it. Something like this:

pawn Код:

CMD:healall(playerid, params[])
{
    SendClientMessage(playerid, COLOR_WHITE, "[SERVER] Everyone is getting healed in 10seconds!");
    SetTimer("heal", 10000, false); 
    return 1;
}
 
forward heal();
public heal()
{
    // Here your heal code.
    // Untested
}
