Fruit

. . . the fruit of man's earthly existence, which is the recognition of the one true God . . .

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 344-345

One who performeth neither good deeds nor acts of worship is like unto a tree which beareth no fruit, and an action which leaveth no trace. Whosoever experienceth the holy ecstasy of worship will refuse to barter such an act or any praise of God for all that existeth in the world.

Bahá’u’lláh, The Importance of Obligatory Prayer and Fasting

The basest of men are they that yield no fruit on earth. Such men are verily counted as among the dead, nay better are the dead in the sight of God than those idle and worthless souls.

Bahá’u’lláh, The Persian Hidden Words #81

There are many things which will, if neglected, be wasted, and come to nothing. How often in this world do we see a child who has lost his parents and who, unless attention be devoted to his education and training, can produce no fruit. And better off dead than alive is he who produceth no fruit.

Bahá’u’lláh, The Compilation of Compilations vol. I, p. 247

The fleeting hours of man's life on earth pass swiftly by and the little that still remaineth shall come to an end, but that which endureth and lasteth for evermore is the fruit that man reapeth from his servitude at the Divine Threshold.

‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 234

The Tree of Life is full of blossoms, leaves and fruits! -- shade thereof is a peace to the soul and a rest to the consciousness. Whosoever is under this Tree will certainly partake of fruit. But shade trees are many in the forest, which, though fresh and verdant, are, nevertheless, fruitless. This truth shall finally become clear and manifest unto thee.
