المحسن
كلمة (المحسن) في اللغة اسم فاعل من الإحسان، وهو إما بمعنى إحسان...
‘Abdullāh ibn ‘Amr ibn al-‘Ās (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Successful is the one who enters Islam and is provided with mere subsistence and Allah makes him content with what He has given him." Abu Muhammad Fadalah ibn ‘Ubayd al-Ansāri (may Allah be pleased with him) reported that he heard the Messenger (may Allah's peace and blessings be upon him) say: "Blissful is the one who is guided to Islam and possesses mere subsistence and shows contentment."
Tūba, a tree in Paradise, is glad tidings for one who has been guided to Islam and his provisions are barely sufficient for him, not less to keep him distracted or more to make him transgress. It is a complete favor by Allah, the Almighty, when He endows us with sustenance that both suffices us and prevents us from transgression.
