(So he (the disbeliever) neither believed nor prayed! But on the contrary, he belied and turned away!)(75:31-32),
وَأَعْطَى قَلِيلاً وَأَكْدَى
(And gave a little, then stopped) Ibn `Abbas said, "Gave a little, then stopped giving." Similar was said by Mujahid, Sa`id bin Jubayr, `Ikrimah, Qatadah and several others. `Ikrimah and Sa`id said: "Like the case of a people who dig a well, during the course of which they find a rock preventing them from completing their work. So they say, `We are finished' and they abandon the work." Allah's statement,
وَأَعْطَىٰ قَلِيلًا وَأَكْدَىٰ (and gave a little, and stopped? ...53:34) The word akda is derived from kudyah which refers to a hard or stony piece of ground or clod that appears in the course of digging a well or a trench. As a result, the digger cannot dig any further. Thus the meaning of the verse is that at first he gave a little, then he stopped giving. In view of the incident narrated under the heading of "Background of Revelation", the meaning is quite clear. [ For the person in that incident paid a little amount and then stopped payment.] Apart from this meaning, Sayyidna Mujahid, Said Ibn Jubair, ` Ikrimah, Qatadah and others interpret this word to imply that a person spent a little in Allah's way, then stopped it; or at first he was somewhat inclined towards Allah's obedience, and he obeyed Him for a while, and then gave it up [ vide Ibn Kathir ].
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 32–34
Man has been created with human weaknesses. So, it is not required that he be as pure as the angels. Almighty God has given full guidance to man as to what he should do and what he should not. However, man may be pardoned in the case of lesser offences (lamam), i.e. indulging in some mischief because of fleeting emotion, on the condition that he should immediately realise his lapse and, being ashamed of it, seek pardon of his Lord.
