Iman and Akida

Iman is Quarinic word but Akida is neither Quaranic nor Hadid word. According to the Quaran Iman is sighted in different Surahs like:

“O you who believe! Believe in Allah, and His Messenger (Muhammad), and the Book (the Qur’an) which He has sent down to His Messenger, and the Scriptures which He sent down to those before (him); and whosever disbelieves in Allah, His Angels, His Books, His Messengers, and the Last Day, then indeed he has strayed far away.”
Surah An Nisa 4:136

Iman is a set of basic beliefs

The set of basic beliefs are (a) there is no Illah but One Allah (swt.) (b) Al Ghaib (c) His Angels (d) His Messengers and last Messenger Mohammad (pbah) (e) His revealed Books and Scriptures Injil, Towrat, Zabur and Quran (as final revelation) (f) The day of Resurrection (Hereafter) (g) Al Qadar (h) Salah (total submission to Almighty Allah (swt) (i) All Righteous Deeds according to the Quran etc.

The phrases “Yea Ayeuhal Lazina Amanu (Faith)” and “Amelus Salihat” (Righteous Deed) are mentioned side by side in forty nine (49) verses in the Quran.
The relationship between Iman (Faith) and Amelus Salihat (Righteous Deeds) is of the seed and the tree. Unless the seed is sown in the soil no tree can growing out of it. But if the seed is in the soil and no tree is growing out of it, it would mean that the seed is lost in the soil.
Further Messengers of Allah (swt) were sent to call people to Islam, practice and establish righteous deeds according to the message revealed from Allah (swt).

“O you who believe! enter perfectly into Islam, whole-heartedly; and follow not the footsteps of the Shaitan Verily, he is to you a plain enemy”. Surah-Baqarah 2:208

“Akida” is a Arabic word which has been used by Islamic Scholars/ Muhaddasin to understand Iman like in English it is “Faith” in Bangla it is “Bishas”. “Iman" is verymos comprehensive word but “Akida” is used to explain “Iman” but not so comprehensive.
