Shaykh Muhammad Nasiruddin Al-Albani was asked:
“May Allah increase you in virtue. Some people ask why is it called Khutbatul-Haajah [the speech of the need]. It is [the sermon] that begins with:
إِنَّ الْحَمْدَ لِلَّهِ نَحْمَدُهُ وَنَسْتَعِينُهُ
“Verily all praise is due to Allah, we praise Him, seek His forgiveness…” etc.
“I was afraid you were going to complete it. However, may Allah reward you for summarizing it. It is called this because you deliver a sermon for a need. If I, for example, attend a sitting in your house or the house of another and I want my speech to reach the depths of your heart, then I will begin my speech with the speech of the need. This is because my need is for my speech to reach your hearts. It is not only [for the speech] to enter one ear and come out the other. So like this, it was called [the speech of the need]” End translation. [Mutafarriqaat no. 1]
