Śrāddha-kalpa: Dāna-phala-nirdeśa
Gifts in Śrāddha and Their Fruits
दत्त्वा मोदन्ति ते स्वर्गे नित्यमाचन्द्रतारकम् / स्वास्तीर्णं शयनं दत्त्वा श्राद्धेरत्नविभूषितम्
dattvā modanti te svarge nityamācandratārakam / svāstīrṇaṃ śayanaṃ dattvā śrāddheratnavibhūṣitam
Having given thus, they rejoice in heaven for as long as the moon and stars endure. In the śrāddha, gifting a well-spread bed adorned with jewels yields the same reward.
