Tafsr al-Jallayn("Tafsir of the two Jalals") is a classicalSunnitafsirof theQur'an, composed first by Jalal ad-Din al-Mahalli in 1459 and then completed by his studentJalal ad-Din as-Suyutiin 1505, thus its name, which means "Tafsir of the two Jalals". It is recognised as one of the most popular exegeses of the Qur'an today,[1]due to its simple style[1]and its conciseness: It being only one volume in length. An English translation by Aisha Bewley was published in 2007.

Praise be to God, is a predicate of a nominal clause, the content of which is intended to extol God [by stating that]: He possesses the praise of all creatures, or that He [alone] deserves their praise. God is a proper noun for the One truly worthy of worship; Lord of all Worlds, that is, [He is] the One Who owns all of creation: humans, jinn, angels, animals and others as well, each of which may be referred to as a world; one says the world of men, or world of the jinn etc. This plural form with the y and the nn [sc. lamn] is used to denote, predominantly, cognizant beings (l ilm). The expression [lamn] relates to [the term] sign (alma), since it is an indication of the One that created it.
