Which Scriptures say that by chanting Lord's name during the time of one's death one can attain "Moksha"?

Question

In Bhagawat Gita Sri Krishna says that one who remembers the Supreme Lord and Pranava(OM) while dying reaches the higher states of bliss or the Supreme Lord Himself.

ओमित्येकाक्षरं ब्रह्म व्याहरन्मामनुस्मरन् । यः प्रयाति त्यजन्देहं स याति परमां गतिम् ।। – Shrimadbhagwadgita, Adhyaya 8, Shloka 13

Meaning-Meaning : (Shrikrushna says) The one who dies while chanting ‘Om’ and remembering me is elevated to a very high level after death.

अन्तकाले च मामेव स्मरन्मुक्त्वा कलेवरम् । यः प्रयाति स मद्भावं याति नास्त्यत्र संशयः ।। – Shrimadbhagwadgita, Adhyaya 8, Shloka 5

Meaning : (Shrikrushna says) There is no doubt that the one who remembers me while dying reaches me.

Question-Are there any other Scriptures that say by chanting Lord's name while dying one can attain moksha(liberation)?

Answer 1

This Brahma Vaivarta Purana chapter states that, one, who chants the name "Shiva", during his/her dying moments, is sure to attain moksha.

Shri Krishna then revealed the excellent value of Shiva Linga Sthapana or establishing a Shiva Linga; he said: Maha Deva Maha Deva Maha Deveti vaadinah, Paschaadyaami Mahaastrasto naama shravana lobhatah, Shiveti mantramucchharya praanamstyajati yo narah/ Koti janmaarjitaat Paapaanmukto muktim prayaati sah, Shivam kalyaana vachanam kalyaanam kalyaanam Muktivaachikam/ Yaatsattha Prabhavettena sa Shivah parikeertitah/ (If some body recites Maha Deva, Maha Deva and Maha Deva, I am tempted to be behind him and follow him; if somebody takes Shiva's name at the time of his death, that person would be freed from the sins committed by his/her previous crores of lives and most certainly secure Moksha. The word Shiva stands for Kalyana or Propitiousness and the word Kalyana denotes Mukti. Also the letter Shi stood for Paapa naashan and Va for Moksha

Answer 2

The story of Ajamila in Bhagawata Purana is an example of the power of chanting the Lord's Name in the last moments of life, even if accidentally. Although the reference is not directly to Moksha, the Vishnudutas avert the immediate mortality of Ajamila, because he chanted the Lord's Name in the last moment.

Of course, the inner significance is that, to be able to chant the Lord's Name at the time of death, one needs to train the mind throughout the life. Sri Ramakrishna mentions a story to illustrate this point about training the mind to chant the Lord's name. A businessman named all his four sons after the names of Lord Narayana, in the hope that, like Ajamila, he will call out one of those names in his last moments, and thereby attain liberation. In the last moment, he called out the names of all the four sons. While they reached his bedside, he exclaimed, 'You fellows! If all of you come here to my bedside, who will take care of the business ?' . And he breathed his last!. He finally thought of his money, instead of chanting the Lord's Name.

Answer 3

(Not specific to chanting name of Krishna), I'm here quoting verse which has similar meaning/preaching to that of Bhagavad-Gita (which is believed to be an essene of Upanishads) you've mentioned.

Chhandogya Upanishad : Adhyaya 3, Khanda 14 (also known as Shandilya Vidya (which Starts from popular Upanidhadic declaration : Sarva Khalvidam Brahman), Verse 14:

सर्वकर्मा सर्वकामः सर्वगन्धः सर्वरसः सर्वमिदमभ्यात्तोऽवाक्यनादर एष म आत्मान्तर्हृदय एतद्ब्रह्मैतमितः प्रेत्याभिसंभवितास्मीति यस्य स्यादद्धा न विचिकित्सास्तीति ह स्माह शाण्डिल्यः शाण्डिल्यः ॥ ३.१४.४॥

4. He whose creation is this universe, who cherishes all desires, who contains all odours, who is endowed with all tastes, who embraces all this, who never speaks and who is without longing-He is my Self within the heart, He is that Brahman. When I shall have departed hence I shall certainly reach Him: one who has this faith and has no doubt will certainly attain to that Godhead. Thus said Sandilya, yea, thus he said.
