No, that is not what IslamQA is promoting. Shaykh al-Munajjid is a scholar who knows that when something becomes Fardh, there is no "checking the state of the heart" before doing it. It has to be done immediately. If a person has the money and ability to go on Hajj, it becomes Fardh upon him immediately. He can't say that he's going to first "check the state of his heart" before he goes on Hajj.
Also, people who say that you must first purify your Nafs before going on Jihaad:
This is a fallacy. It's stipulating an impossible condition with the deliberate intention of stopping something. It's like a person saying, "I'll give a Bayaan in a Masjid the day pigs grow wings and fly." You know that's not going to happen, so you make up a condition like that.
Now, anyone who has studied `Ilm-ut-Tasawwuf knows that Islaah-e-Nafs and Jihaad against the Nafs is lifelong; it never ends until the day you die. So to say a person can only go for Jihaad after he has done Islaah of the Nafs is asking for something that is impossible; the person will continue doing Islaah of his Nafs till the day he leaves this Dunyaa. If Islaah of the Nafs had been a condition for Jihaad fee Sabeelillaah, no Jihaad would ever have taken place on this Dunyaa, because no one had achieved complete purity of the Nafs before doing so. Even in the time of Sahaabah-e-Kiraam, there was a Sahaabi who fought in Jihaad and yet fell into drinking Khamr at one occasion, and was given the Shar`i punishment for it.
IslamQA is not promoting the idea that a person must first do Islaah of his Nafs before going in Jihaad. He is saying, if you read the original Arabic text and understand the Siyaaq and Sabaaq of the Kalaam, that a person's going out in Jihaad
is Islaah of the Nafs. That in itself is Jihaad against the Nafs. Like we mentioned, Jihaad against the Nafs and Jihaad on the battlefield go hand-in-hand.
