Surah Al-Najm 53:14

عِندَ سِدْرَةِ الْمُنتَهَى ٰعِندَهَا جَنَّةُ الْمَأْوَىٰ

53:14 Sidrahسِدْرَةِ - the lote-tree. The leaves of this tree are always clean and possess the ability to preserve a dead body for some time due to their anti-septic properties. The lote-tree is immune to the poisonous effects. No specific lote-tree in a particular place in Arabia is referred to. Such a notion is refuted by the next statement, “Near where also is the garden, which is the real eternal abode”. Explaining the expression, Râghib suggests that owing to the abundance of its leafy shade, the word appears in the Qur’ân as well as in the sayings of the Holy Prophet (pbuh) as a symbol of the shade of Paradise (56:28). It is an exalted “place”, which was chosen for the Holy Prophet (pbuh) for Divine favours. The qualifying term al-Muntahâ الْمُنتَهَى - at the farthest end, is indicative of the fact it is a place beyond the confines of human knowledge. Sadirسَدَر is derived from the same root meaning the sea (Tâj). Thus, the expression indicates that at that stage a sea of endless vistas of Divine knowledge and eternal realities were opened up for him. It also means to signify that the spiritual knowledge and intellect of the Holy Prophet (pbuh) was perfect, of a quality that could exercise antidote influences on the suffering humanity (Ibn Jarîr). The verse also signifies that the Revelation given to the Holy Prophet (pbuh) in the form of the Holy Qur’ân is not only itself immune like the lote-tree, but is eminently fitted to save and preserve humankind from becoming corrupt and spiritually dead.
