Parents

Beware lest ye commit that which would sadden the hearts of your fathers and mothers. Follow ye the path of Truth which indeed is a straight path. Should anyone give you a choice between the opportunity to render a service to Me and a service to them, choose ye to serve them, and let such service be a path leading you to Me. This is My exhortation and command unto thee. Observe therefore that which thy Lord, the Mighty, the Gracious, hath prescribed unto thee.

Bahá’u’lláh, Lights of Guidance, p. 230

One of the distinguishing characteristics of this most great Dispensation is that the kin of such as have recognized and embraced the truth of this Revelation and have, in the glory of His name, the Sovereign Lord, quaffed the choice, sealed wine from the chalice of the love of the one true God, will, upon their death, if they are outwardly non-believers, be graciously invested with divine forgiveness and partake of the ocean of His Mercy. This bounty, however, will be vouchsafed only to such souls as have inflicted no harm upon Him Who is the Sovereign Truth nor upon His loved ones. Thus hath it been ordained by Him Who is the Lord of the Throne on High and the Ruler of this world and of the world to come.

Bahá’u’lláh, The Compilation of Compilations vol. I, p. 386

Say, O My people! Show honour to your parents and pay homage to them. This will cause blessings to descend upon you from the clouds of the bounty of your Lord, the Exalted, the Great.

Bahá’u’lláh, Lights of Guidance, p. 229

Thou hast mentioned the station of parents in the next world. One of the special bounties of this Revelation is that whoever accepteth the Dayspring of the Cause, his parents, although they may not have attained the recognition of the Revelation, the splendours of the Sun of divine favor will be vouchsafed unto them. This is one of His bounties bestowed upon His lovers. Render thanks and be of those who are grateful.

Bahá’u’lláh, quoted in The Universal House of Justice, 1991 Aug 28, The Condition of non-Bahá’í Relatives after Death

We have caused to return to thy home as a token of Our Mercy unto thy mother, inasmuch as We found her overwhelmed with sorrow. We have enjoined you in the Book 'to worship no one but God and to show kindness to your parents'. Thus hath the one true God spoken and the decree hath been fulfilled by the Almighty, the All-Wise. Therefore We have caused thee to return unto her and unto thy sister, that your mother's eyes may thereby be cheered, and she may be of the thankful.

Bahá’u’lláh, Lights of Guidance, p. 229

When We learned of her sadness, We directed thee to return unto her, as a token of mercy unto thee from Our presence, and as an admonishment for others.
