Allah's saying:
[مَن كَانَ يَرْجُو
لِقَآءَ اللَّهِ]
(Whoever hopes in meeting with Allah,) means, in the Hereafter, and does
righteous deeds, and hopes for a great reward with Allah, then Allah will
fulfill his hopes and reward him for his deeds in full. This will undoubtedly
come to pass, for He is the One Who hears all supplications, He knows and
understands the needs of all created beings. Allah says:
[مَن كَانَ يَرْجُو
لِقَآءَ اللَّهِ فَإِنَّ أَجَلَ اللَّهِ لآتٍ وَهُوَ السَّمِيعُ الْعَلِيمُ
]
(Whoever hopes in meeting with Allah, then Allah's term is surely coming, and
He is the All-Hearer, the All-Knower.)
[وَمَن جَاهَدَ
فَإِنَّمَا يُجَـهِدُ لِنَفْسِهِ]
(And whosoever strives, he strives only for himself.) This is like the Ayah,
[مَّنْ عَمِلَ
صَـلِحاً فَلِنَفْسِهِ]
(Whosoever does righteous good deed, it is for himself) (41:46). Whoever does
a righteous deed, the benefit of that deed will come back to him, for Allah has
no need of the deeds of His servants, and even if all of them were to be as
pious as the most pious man among them, that would not add to His dominion in
the slightest. Allah says:
[وَمَن جَاهَدَ
فَإِنَّمَا يُجَـهِدُ لِنَفْسِهِ إِنَّ اللَّهَ لَغَنِىٌّ عَنِ الْعَـلَمِينَ
]
(And whosoever strives, he strives only for himself. Verily, Allah stands not
in need of any of the creatures.) Then Allah tells us that even though He has no
need of His creatures, He is kind and generous to them. He will still give to
those who believe and do righteous deeds the best of rewards, which is that He
will expiate for them their bad deeds, and will reward them according to the
best deeds that they did. He will accept the fewest good deeds and in return for
one good deed will give anything between ten rewards and seven hundred, but for
every bad deed, He will give only one evil merit, or even that He may overlook
and forgive. This is like the Ayah,
[إِنَّ اللَّهَ لاَ
يَظْلِمُ مِثْقَالَ ذَرَّةٍ وَإِن تَكُ حَسَنَةً يُضَـعِفْهَا وَيُؤْتِ مِن
لَّدُنْهُ أَجْراً عَظِيماً ]
(Surely, Allah wrongs not even the weight of a speck of dust, but if there is
any good, He doubles it, and gives from Him a great reward.) (4:40). And He says
here:
[وَالَّذِينَ
ءَامَنُواْ وَعَمِلُواْ الصَّـلِحَـتِ لَنُكَفِّرَنَّ عَنْهُمْ سَيِّئَاتِهِمْ
وَلَنَجْزِيَنَّهُمْ أَحْسَنَ الَّذِى كَانُواْ يَعْمَلُونَ ]
(Those who believe, and do righteous good deeds, surely, We shall expiate
from them their evil deeds and We shall indeed reward them according to the best
of that which they used to do.)
[وَوَصَّيْنَا
الإِنْسَـنَ بِوَالِدَيْهِ حُسْناً وَإِن جَـهَدَاكَ لِتُشْرِكَ بِى مَا لَيْسَ
لَكَ بِهِ عِلْمٌ فَلاَ تُطِعْهُمَآ إِلَىَّ مَرْجِعُكُمْ فَأُنَبِّئُكُم بِمَا
كُنتُمْ تَعْمَلُونَ - وَالَّذِينَ ءَامَنُواْ وَعَمِلُواْ الصَّـلِحَـتِ
لَنُدْخِلَنَّهُمْ فِى الصَّـلِحِينَ ]
(8. And We have enjoined on man to be dutiful to his parents; but if they
strive to make you associate with Me, which you have no knowledge of, then obey
them not. Unto Me is your return and I shall tell you what you used to do.) (9.
And for those who believe and do righteous deeds, surely, We shall admit them
among the righteous.)
