the Messenger of Allah (saas) said: "Allah, the Blessed and Exalted, said: 'Whoever does one good deed will have (the reward of) ten like it and more, and whoever does a bad deed will have one like it, or I will forgive him. Whoever draws near to Me a hand span, I draw near to him an arm's length; whoever comes to Me a forearm's length, I draw near him an arm's length; whoever comes to Me walking, I come to him in a hurry. Whoever meets Me with an earthful of sins, but does not associate anything in worship with Me, I will meet it (i.e., his sins) with forgiveness equal to that.'"  

قَالَ رَسُولُ اللَّهِ ﷺ يَقُولُ اللَّهُ تَبَارَكَ وَتَعَالَى مَنْ جَاءَ بِالْحَسَنَةِ فَلَهُ عَشْرُ أَمْثَالِهَا وَأَزِيدُ وَمَنْ جَاءَ بِالسَّيِّئَةِ فَجَزَاءُ سَيِّئَةٍ مِثْلُهَا أَوْ أَغْفِرُ وَمَنْ تَقَرَّبَ مِنِّي شِبْرًا تَقَرَّبْتُ مِنْهُ ذِرَاعًا وَمَنْ تَقَرَّبَ مِنِّي ذِرَاعًا تَقَرَّبْتُ مِنْهُ بَاعًا وَمَنْ أَتَانِي يَمْشِي أَتَيْتُهُ هَرْوَلَةً وَمَنْ لَقِيَنِي بِقِرَابِ الأَرْضِ خَطِيئَةً ثُمَّ لاَ يُشْرِكُ بِي شَيْئًا لَقِيتُهُ بِمِثْلِهَا مَغْفِرَةً  

the Messenger of Allah (saas) said: "Allah says, 'I am as My slave thinks I am, and I am with him when he mentions Me. If he makes mention of Me to himself, I make mention of him to Myself; and if he makes mention of Me in an assembly, I make mention of him in an assembly better than it. And if he draws to Me a hand-span length, I draw near to him a forearm's length. And if he comes to Me walking, I go to him in a hurry."  

قَالَ رَسُولُ اللَّهِ ﷺ يَقُولُ اللَّهُ سُبْحَانَهُ أَنَا عِنْدَ ظَنِّ عَبْدِي بِي وَأَنَا مَعَهُ حِينَ يَذْكُرُنِي فَإِنْ ذَكَرَنِي فِي نَفْسِهِ ذَكَرْتُهُ فِي نَفْسِي وَإِنْ ذَكَرَنِي فِي مَلإٍ ذَكَرْتُهُ فِي مَلإٍ خَيْرٍ مِنْهُمْ وَإِنِ اقْتَرَبَ إِلَىَّ شِبْرًا اقْتَرَبْتُ إِلَيْهِ ذِرَاعًا وَإِنْ أَتَانِي يَمْشِي أَتَيْتُهُ هَرْوَلَةً  

of Allah (saas) said: "Every deed of the son of Adam will be multiplied for him, between ten and seven hundred times for each merit. Allah said: 'Except for fasting, for it is for Me and I shall reward for it.'" (sahih)  

قَالَ رَسُولُ اللَّهِ ﷺ كُلُّ عَمَلِ ابْنِ آدَمَ يُضَاعَفُ لَهُ الْحَسَنَةُ بِعَشْرِ أَمْثَالِهَا إِلَى سَبْعِمِائَةِ ضِعْفٍ قَالَ اللَّهُ سُبْحَانَهُ إِلاَّ الصَّوْمَ فَإِنَّهُ لِي وَأَنَا أَجْزِي بِهِ
