২০. যারা
মুমিন,
তারা বলেঃ একটি সূরা নাযিল হয় না কেন?
অতঃপর যখন কোন দ্ব্যর্থহীন
সূরা নাযিল হয় এবং তাতে জেহাদের উল্লেখ করা হয়, তখন যাদের অন্তরে রোগ আছে,
আপনি তাদেরকে মৃত্যুভয়ে মূর্ছাপ্রাপ্ত মানুষের মত আপনার দিকে তাকিয়ে
থাকতে
দেখবেন।
সুতরাং ধ্বংস তাদের জন্যে।
২১. তাদের
আনুগত্য ও মিষ্ট বাক্য জানা আছে। অতএব,
জেহাদের সিন্ধান্ত হলে যদি তারা
আল্লাহর প্রতি পদত্ত অংগীকার পূর্ণ করে,
তবে তাদের জন্যে তা মঙ্গলজনক হবে।
Ayat 20. Those (Hypocrites) who believe say: "Why is not a Surah (chapter of the Qur’an) sent down (for us)? But when a decisive Surah (explaining and ordering things) is sent down, and fighting (Jihad holy
fighting in Allah’s Cause) is mentioned (i.e. ordained) therein, you
will see those in whose hearts is a disease (of hypocrisy) looking at
you with a look of one fainting to death. But it was better for them
(hypocrites, to listen to Allah and to obey Him).
Ayat 21. Obedience (to Allah) and good words (were better for them). And when the matter (preparation for Jihad) is resolved on, then if they had been true to Allah, it would have been better for them.
Tafseer of Surah Muhammad 
Peace be upon him] Ayat 20 and 21. Those
who believe ay, "Why is not a Surah sent down (for us)?" But when a
Surah of basic or categorical meaning is revealed, and fighting is
mentioned therein, thou wilt see those in whose hearts is a disease
looking at thee with a look of one in swoon at the approach of death.
But more fitting for them- The
men of faith and loyalty are eager and anxious to get a command to
serve the Cause even if it be at the sacrifice of their lives. Not so
the Hypocrites, "those in whose hearts is a disease". They are mortally
afraid as mentioned below. Cf. 3:7. The defense of truth and
righteousness at all sacrifice, when a definite and categorical command
issues from Amir al Mu'minin is a fundamental condition of enlistment in
the cause of Allah. It is true that Punishment and Judgment belong to
Allah alone; but our mettle and fidelity have to be tested, (see verse 4
above), and Allah uses human agency in human affairs. Cf. 2:10.
The disease is hypocrisy, disloyalty to the Cause, want of courage and
of the spirit of self-sacrifice, want of true understanding. Ayat 21. Were it to obey and say what is just, and when a matter is resolved on, it were best for them if they were true to Allah. The
resolution is not taken except under guidance from Allah. Those,
therefore, who fail to implement it by their own effort and sacrifice,
are not true to Allah. And such disloyalty or cowardice is not even good
for them from a worldly point of view. With what face can they meet
their friends after their disgraceful conduct?
Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah
[SAWW](PBUH) said, "He who dies without having fought in the Cause of
Allah or without having thought of doing so, will die with one
characteristic of hypocrisy in him.'' [Muslim Hadith # 1910].
Lesson: as mentioned above in Surah Muhammad 
Peace be upon him] Ayat 20. Those (Hypocrites) who believe say: "Why is not a Surah (chapter of the Qur’an) sent down (for us)?” We
learn from this Hadith that it is a different matter that one may not
get a chance to take part in Jihad, but it would be a hypocritical
attitude if one does not ever think that if an opportunity ever comes in
his way, he will certainly go for Jihad in the way of Allah against the
infidels. The reason to that is that, to stay back at home at the time
of Jihad was a habit of the hypocrites. In the light of this, Imam
Al-Qurtubi has stated the principle that if one is not capable of doing
some virtuous deeds, he should then make a resolve that whenever he will
be capable of it, he will do that deed, so that his intention takes the
place of his act. He who neither performs a good deed nor aspires for
it, has a hypocritical disposition. This is especially true of a Muslim
who does not even aspire to take part in Jihad. Such a Muslim develops a
resemblance with hypocrites.
[SAWW](PBUH)
and he asked me, "Have you come to inquire about piety?'' I replied in
the affirmative. Then he said, "Ask your heart regarding it. Piety is
that which contents the soul and comforts the heart, and sin is that
which causes doubts and perturbs the heart, even if people pronounce it
lawful and give you verdicts on such matters again and again.'' [Masnad Ahmad, Imam Ahmad Hadith # 228/4].
