Manava Dharmashastra 3.168

3.168

yāvato brāhmaṇān spṛśatyaṅgaiḥ, paṅkti gataḥ | atrāpyaṅgasya sparśanaṃ na vivakṣitam, kiṃ tarhi pūrvavattaddeśasaṃnidhiḥ | paurtikaṃ phalam | pūrte bhavaṃ paurtikam | barhirvedidānādyatphalaṃ tatpaurtikam |

Medhātithi’s commentary (manubhāṣya):
As many Brāhmaṇas he may happen to touch with his limbs,—when he happens to enter the same line with them;—here also the actual touching of the body is not meant; mere presence at the place is meant.

‘Reward relating to charity’—i.e., the rewards that follow from gifts made outside the ‘sacrificial altar.—(178)
