It is narrated from Alaa bin Ziyad that a man asked Sayyiduna Umar bin Al-Khattab (may Allah be pleased with him): My heir is a kalalah (one who has no children), can I make a bequest of half (of my wealth)? Sayyiduna Umar (may Allah be pleased with him) said: No. He said: Of one third? He replied: No. He said: Of one fourth? He replied: No. He said: Of one fifth? He replied: No, until he reached one tenth, then he said: Yes, you can make a bequest of one tenth.
