Shaykh Al-Albaani (rahimahullah rahmatan waasi'a) said, "And in reality, my entire goal in this life–after carrying out the obligatory duties and rights that Allaah has made incumbent upon me–is but to acquaint the Muslims with the accurate biography [Seerah] of the Prophet صلى الله عليه وسلم from every aspect as far as I am able, by teaching [them], lecturing and writing, and to urge them to take him as the definitive example for themselves, as Allaah the Most High has asked them to, as occurs in His Saying:
لَّقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ
لِّمَن كَانَ يَرْجُو اللَّهَ وَالْيَوْمَ الْآخِرَ وَذَكَرَ اللَّهَ كَثِيرًا
"There has certainly been for you in the Messenger of Allaah an excellent example for anyone whose hope is in Allaah and the Last Day and [who] remembers Allaah much."
And in that lies their happiness in this world and the Hereafter."
