You are talking about the Phalashruthi portion of The Vishnu Sahasranamam.
I guess there is no harm to recite it if there is time.
Maybe someone else more learned should answer this.
i put the phala shruti below so others will understand what you are talking about
Itidam keerthanasya kesavasya mahatmana,
Namnam sahasram diwyanamaseshesna prakeerthitham. 1
Thus was told,
All the holy thousand names,
Of Kesava who is great.
Ya tdam srunyuan nityam yaschapi parikeerthayed,
Nasubham prapunayad kinchid Soamuthre ha cha manava. 2
He who hears or sings,
It all without fail,
In all days of the year,
Will never get in to bad,
In this life and after.
Vedantago brahmana syad kshatriyo vijayi bhaved,
Vaisyo dhana samruddha syachyutha sugapnuyad. 3
The Brahmin will get knowledge,
The kshatriya will get victory,
The vaisya will get wealth,
The shudra will get pleasures,
By reading these.
Dharmarthi prapnuyad dharmam, artharthi cha arthamapnuyad,
Kamanvapnuyad kami, prajarthi chapnuyad prajam. 4
He who seeks Dharma,
He who seeks wealth,
He who seeks pleasures,
He who seeks children,
Will all without fail,
Get what they want.
Bhakthiman ya sadaothaya, suchistad gatha manasa,
Sahasram vasudevasya namnamedat prakeerthayed. 5
Yasa prapnodhi vipulam yadi pradanya meva cha,
Achalam sriyamapnodhi sryaprapnothyanuttamam. 6
Na bhayam kwachidapnodhi veerya tejascha vindhati,
Bhavatyarogo dyuthiman bala roopa gunanvidha. 7
Rogartho muchayade rogat, bhaddo muchyathe bandanath,
Bhayan muchyathe bheedasthu, muchyadepanna apada. 8
He who sings the thousand names of Vasudeva,
With utmost devotion,
After he rises in the morn,
With a mind tied in Him always,
Will get fame without fail,
Will be first in what he does,
Will get riches that last,
Would attain salvation from these bonds,
Will never be afraid of anything,
Will be bubbling with vim and valour,
Will not get any ills,
Will be handsome forever,
Will have all the virtues in this wide world,
And he who is ill will get cured,
He who is bound will be free,
He who is afraid, will get rid of fear,
He who is in danger, will be safe.
Durganyadarthyasu purusha purushottamam,
Stuvan nama sahasrena nityam bhakthi samanvida. 9
He who chants these holy thousand names,
With devotion to Purushottama,
Will cross the miseries,
That cannot be crossed
Vasudevasryo marthyo vasudeva parayana,
Sarva papa vishudhatma yati brahma sanathanam. 10
The man who nears Vasudeva,
The man who takes Him as shelter,
Would get rid of all sins,
And become purer than the pure,
And will reach Brahmam,
Which existed forever.
Na vasudevabhaktanamasubham vidyate kwachit
Janma nrutyu jara vyadhi bhayam naivopa jayade. 11
The devotees of Vasudeva the great,
Never fall into days that are difficult,
And never forever suffer,
Of birth, death, old age and fear.
Imam stavamaddeyana sraddha bhakthi samanvidha,
Yujyedathma sukha kshanthi sri dhrithi smrithi keerthibhi. 12
He who sings these names with devotion,
And with Bhakthi,
Will get pleasure the great,
Patience to allure,
Wealth to attract,
Bravery and memory to excel.
Na krodho na cha matsarya na shubha mati,
Bhavanthi kritha punyanam bhakthanam puroshottame. 13
The devotee of the Lord Purushottama,
Has neither anger nor fear,
Nor avarice and nor bad thoughts.
Dhyau sachandrarka nakshatra kham diso bhur mahadathi.
Vasudevasya veeryena vidhrithani mahatmana. 14
All this world of sun and stars,
Moon and sky, Sea and the directions,
Are but borne by valour the great,
Of the great god Vasudeva.
Sasurasura gandharwa, sayakshoraga rahshasam,
Jagaddese vartatedam krishnasya sacharacharam. 15
All this world,
Which moves and moves not,
And which has devas, rakshasas and Gandharwas,
And also asuras and nagas,
Is with Lord Krishna without fail.
Indriyani mano bhuddhi satvam tejo bala dhruti.
Vasudevatmakanyahu kshetram ksheragna eve cha. 16
The learned ones say,
That all the limbs,
Mind, wisdom, and thought,
And also strength, bravery, body and the soul,
Are full of Vasudeva.
Sarvagamanamachara pradamm parikalpathe,
Achara prabhavo dharma dharmasya prabhurachyutha. 17
Rule of life was first born
And from it came Dharma,
And from it came Achyutha the Lord.
Hrishaya pitaro deva mahabhootani dhatava,
Jangamajangamam chedam jagannarayanodbhavam. 18
All the sages,
All the ancestors,
All the devas,
All the five elements,
All the pleasures,
All the luck,
All that moves,
All that does not move,
All came only,
From the great Narayana.
Yogo gnanan thada sankhyam vidhya shilpadhi karma cha
Veda shastradi vignanam death sravam janardhanath. 19
The art of Yoga
And the science of Sankhya.
The treasure of knowledge.
The divine art of sculpture.
And all Vedas and sciences,
All these came from Janardhana.
Eko vishnu mahadbhutham pradag bhutanyanekasa,
Treem lokan vyapya bhutatma bhungte viswabhugavyaya. 20
Vishnu is many,
But He is one,
And he divides himself,
And exists in all beings,
That is in three worlds,
And rules all of them,
Without death and decay.
Imam stavam bhagavatho vishnur vyasena keerthitham,
Padedya icched purusha sreys prapthum sukhani cha. 21
He who desires fame and pleasure,
Should chant these verses, sung by Vyasa,
Of this great stotra of Vishnu without fail.
Visweswaramajam devam jagatha prabhumavyayam,
Bhajanthi ye pushkaraksham na te yanthi parabhavam
Na te yanthi parabhava om na ithi. 22
He will never fail,
Who sings the praise of the Lord,
Of this universe,
Who does not have birth,
Who is always stable,
And who shines and sparkles,
And has lotus eyes.
Om Nama He will not fail.
