Weak are the seeker/pursuer and the one who is sought/pursued

عوذ بالله من الشيطان الرجيم 

Al-Hajj 22:73

يَٰٓأَيُّهَا ٱلنَّاسُ ضُرِبَ مَثَلٌ فَٱسْتَمِعُوا۟ لَهُۥٓۚ إِنَّ ٱلَّذِينَ تَدْعُونَ مِن دُونِ ٱللَّهِ لَن يَخْلُقُوا۟ ذُبَابًا وَلَوِ ٱجْتَمَعُوا۟ لَهُۥۖ وَإِن يَسْلُبْهُمُ ٱلذُّبَابُ شَيْـًٔا لَّا يَسْتَنقِذُوهُ مِنْهُۚ ضَعُفَ ٱلطَّالِبُ وَٱلْمَطْلُوبُ 

O people, an example is presented, so listen to it. Indeed, those you invoke besides Allah will never create [as much as] a fly, even if they gathered together for that purpose. And if the fly should steal away from them a [tiny] thing, they could not recover it from him. Weak are the pursuer and pursued.

Mankind is Created Weak

Aaoodhoo billahe minashaitan rajeem 

 An-Nisa' 4:27

وَٱللَّهُ يُرِيدُ أَن يَتُوبَ عَلَيْكُمْ وَيُرِيدُ ٱلَّذِينَ يَتَّبِعُونَ ٱلشَّهَوَٰتِ أَن تَمِيلُوا مَيْلًا عَظِيمًا 

Allah wants to accept your repentance, but those who follow [their] passions want you to digress [into] a great deviation.

 An-Nisa' 4:28

يُرِيدُ ٱللَّهُ أَن يُخَفِّفَ عَنكُمْۚ وَخُلِقَ ٱلْإِنسَٰنُ ضَعِيفًا 

And Allah wants to lighten for you [your difficulties]; and mankind was created weak.

Many times It happens that I want to achieve something big. Something big in ayahs of Allah but seems ridiculous in terms of worldly gain. For example living like Prophet Muhammad saw in a small home, eating like him meaning eating just how much is needed, wearing like him meaning not wearing extravagant dresses, spending like him meaning not hoarding any money or gold for family and children, trusting on Allah like him, strengthening the family ties ignoring their injustices, working like him meaning taking care of my chores myself without depending on maids etc.  I might have good intention but I don't know how-to achieve it. I share the idea with somebody and that somebody is under the influence of Satan right now and starts discouraging me about it and I loose the courage. That's where ayah 27, 28 helps. We are created weak and we get even weaker by doing all extra stuff that Prophet Muhammad saw didn't do and then deviate from main purpose. May Allah save us all from those who follow their desires and May Allah strengthen our iman. Ameen.

Seeker and sought are both weak

اعوذ بالله من الشيطن الرجيم

Surah 22. Al-Hajj, Verse 73:

يَا أَيُّهَا النَّاسُ ضُرِبَ مَثَلٌ فَاسْتَمِعُوا لَهُ إِنَّ الَّذِينَ تَدْعُونَ مِن دُونِ اللَّهِ لَن يَخْلُقُوا ذُبَابًا وَلَوِ اجْتَمَعُوا لَهُ وَإِن يَسْلُبْهُمُ الذُّبَابُ شَيْئًا لَّا يَسْتَنقِذُوهُ مِنْهُ ضَعُفَ الطَّالِبُ وَالْمَطْلُوبُ

Translation:

O mankind! A similitude has been coined, so listen to it (carefully): Verily! Those on whom you call besides Allah, cannot create (even) a fly, even though they combine together for the purpose. And if the fly snatched away a thing from them, they would have no power to release it from the fly. So weak are (both) the seeker and the sought.

Weak ones will say to arrogant ones

اعوذ بالله من الشيطن الرجيم

Surah 14. Ibrahim, Verse 21:

وَبَرَزُوا لِلَّهِ جَمِيعًا فَقَالَ الضُّعَفَاءُ لِلَّذِينَ اسْتَكْبَرُوا إِنَّا كُنَّا لَكُمْ تَبَعًا فَهَلْ أَنتُم مُّغْنُونَ عَنَّا مِنْ عَذَابِ اللَّهِ مِن شَيْءٍ قَالُوا لَوْ هَدَانَا اللَّهُ لَهَدَيْنَاكُمْ سَوَاءٌ عَلَيْنَا أَجَزِعْنَا أَمْ صَبَرْنَا مَا لَنَا مِن مَّحِيصٍ

Translation:

And they all shall appear before Allah (on the Day of Resurrection) then the weak will say to those who were arrogant (chiefs): "Verily, we were following you; can you avail us anything from Allah's Torment?" They will say: "Had Allah guided us, we would have guided you. It makes no difference to us (now) whether we rage, or bear (these torments) with patience, there is no place of refuge for us."
